Book Description
The book marks the Platinum Jubilee of the Indian Institute of Metals, closely matching independent India's age. It is envisaged as a compilation of technical articles tracing the birth and growth trajectory of metallurgical science, engineering and technology in the nation, attempting a degree of prognostication covering the next quarter of a century. It contains the essence of the metallurgical research and development and industrial progress India has witnessed in the last 75 years. This book comprises technical articles written by industry leaders and eminent technocrats. It includes overviews by distinguished researchers who have strived to build foundations of new metallurgical research and engineering fields. It includes learned writings of persons associated with premier institutions heavily dependent on metallurgy and materials. They have made seminal contributions by nurturing the growth of metallurgical research and industrial production or have made first-hand contributions to building the great organisations we have today. Coinciding with the Platinum Jubilee year of the Indian Institute of Metals, this book brings out the enormous efforts of these individuals representing their organisations to share insights that led to their success as an entity. Similarly, several professionals who significantly contributed to the understanding of metallurgical engineering, have held important positions and steered the national strategic programmes or academically nurtured students in their illustrious careers also share their journey in this book. This book chronicles the significant advances made in the field of metallurgical science, engineering and technology in India, presenting the historical perspective and prospects in the format of a technical volume.

Book Description
Most studies of ancient technology have hitherto been based on the civilisations of the Mediterranean and Middle East, especially those of Egypt, Greece and Rome. In this volume the extraordinarily well preserved remains at three major mining and metal production sites in the Aravalli Hills of Rajasthan (Agucha, Dariba and Zawar) were revealed. At these sites, by survey and archaeological excavation, the authors, studied the long-term development of mining and smelting activity over 3000 years. At Dariba and Agucha silver was mined by the Mauryan Empire on a colossal scale over 2,000 years ago. At Zawar the Mauryan mines seem to have produced mainly zinc oxide, but in the Medieval period zinc metal was produced by advanced processes of high temperature distillation, almost certainly the earliest commercial zinc production in the world. Here the laboratory processes described in the early Indian scientific works were developed into major industrial processes, the birth of chemical industry at least 500 years before similar developments began in Europe. The authors also analyse the decline and rebirth of extractive metallurgy in India.

Book Description
Metals and their knowledge have have been important in historic as well as pre-historic ages. Many of the pre-historic artefacts are still a wonder to the modern man. When we visit places like Ajanta, Ellora caves, Konark Temple at Bhubaneshwar, Taj Mahal at Agra, Qutb Minar and Ashoka Pillar at Delhi, we look with awe the craftsmanship of the sculptors and metal workers. A strong culture of technology is necessary for creation of such masterpieces.The monuments made of stones needed a few basic metal implements: chisels and hammers. How did these originate? Before the making of basic metal tools, stone based tools were only available which were heavy and got blunted easily and could not be used for agriculture. Metal tools are harder, last longer and are re-workable. Thus it is said that with the proliferation of metal usage, agriculture and stock-raising expanded many times. Also the villages prospered and towns came into being.Copper was the first metal man had contact with. The first copper used was native copper. Copper metallurgy in India dates back to the start of the Chalcolithic culture in the sub-continent. The Harappans extensively used Copper and Bronze to make knives, daggers, arrowheads, axes, chisel, bangles, bracelets and beads.The source of metal is the next point to think of. Was the metal obtained in a native state or extracted from ore? Also the usage of flux then to remove gangue as slag needs pondering. The shape and capacity of the furnace used is also important. Whether the metal was used as it is or alloyed with some other metal, is another query? The process of solidification by casting or the object formation by forge-welding/forging is another question. Such questions need to be answered to know about the scientific basis and technical skills of the Copper smelters and smiths in ancient times.But there are no direct answers. Answers are hidden under artefacts, furnaces, slags and other archaeological evidences. World over we find a well-marked sequence of usage of metals: copper-arsenical, copper-tin, bronze, iron, occurs which may suggest a diffusion process. However, we do not get the full sequence and in some parts we go from Neolithic technology to an Early Iron Age civilization. For a long time, the theory of the diffusion of ideas and techniques has been generally. But now, the long held general diffusional thesis for spread of metallurgy has come under cloud. The second metal iron was used in India after Copper and Bronze, as in other parts of the world and in India it was made indigenously. One may recall mastery in metal casting from the Indus times with the shining example of the dancing girl, cast in Bronze by cire purdue process. Subsequently, heavy tools and implements have been found in the copper hoards in the gangetic plains during 2000-1500 BCE. The modern day Zinc was already being produced in India in 12th to 13th centuries in the Zawar region of Rajasthan. The Ashoka Pillar at Mehraulli created in the 4th-5th century CE is a wonder having withstood 1600 monsoons which testifies its extraordinary qualitative feature. Wootz known worldwide as the famous Damascus steel was another product from master craftsmen of India many centuries years ago. The medieval period saw the emphasis on producing war implements and the Shahi Karkhanas came up and master craftsmen from West Asia came to make large iron cannons which started replacing bronze cannons.The remarkable skills of the Indian Metallurgists did get lost to the world during British rule possibly due to the 1857 mutiny after which making of firearms including the famous swords was halted. Mines were closed and even the miners were extinct. The arrival of the British saw the synergy of indigenous Indian metallurgy and western technology. Later came up the Indian Iron and Steel company and Tata Iron and Steel companies.This book is an introduction to the history of metallurgy in India since Ancient times.

Book Description
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Book Description
This textbook is a culmination of multiple efforts of the authors to fill in the gap for offering a required course on Indian Knowledge System (IKS), recently mandated by AICTE. Moreover, the New Education Policy (NEP) has also provided a clear trajectory for imparting IKS in the higher education curriculum, necessitating a book of this kind in several higher education institutions in the country in the days to come. The book seeks to introduce the epistemology and ontology of IKS to the Engineering and Science students in a way they can relate, appreciate and explore further should there be a keen interest in the matter. After a brief section on the key concepts of IKS, the remaining part of the book traces IKS and brings out the applications. After a formal and concise introduction to IKS, the book provides certain foundational concepts applicable across all domains of Science and Engineering. These form the second part. The Science applications are laid out in Part 3, Engineering applications in Part 4 and other important topics in the final part of the book. The authors have rich expertise and background in both 'mainstream issues' and 'traditional knowledge' to present IKS in a contextually relevant fashion. They have delicately balanced the 'why' or 'how' of IKS and the 'what' of IKS. Although the book has been primarily developed for use by the Engineering institutions, the structure and the contents also address the requirement in other University systems (Liberal Arts, Medicine, Science and Management). This textbook incorporates several pedagogical features including a companion website https://www.phindia.com/ introduction_to_indian_knowledge_system that will make learning effective and enjoyable for the students. TARGET AUDIENCE Students at: • Engineering Institutes • Higher Education Institutes
