Book Description
This volume is part of the Ceramic Engineering and Science Proceeding (CESP) series. This series contains a collection of papers dealing with issues in both traditional ceramics (i.e., glass, whitewares, refractories, and porcelain enamel) and advanced ceramics. Topics covered in the area of advanced ceramic include bioceramics, nanomaterials, composites, solid oxide fuel cells, mechanical properties and structural design, advanced ceramic coatings, ceramic armor, porous ceramics, and more.

Book Description
Nitrogen has been partially substituted for oxygen in a wide variety of silicate systems to produce oxynitride glasses with improved properties. Nitrogen contents as high as 12 at% have been achieved. The glass-forming regions in the Y-Si-Al-O-N, Mg-Si-Al-O-N, and Ca-Si-Al-O-N systems have been investigated in detail, and those in the Si-Al-O-N, La-Si-Al-O-N, Li-Si-Al-O-N, and Sc-Si-Al-O-N systems have been studied to a lesser extent. For all compositions there is a consistent variation in properties with nitrogen content. The glass transition temperature, hardness, fracture toughness, and density all increase, and the thermal expansion coefficient decreases with increased nitrogen content. Those data, together with infrared spectroscopic results, are consistent with a structural model in which trivalent nitrogen substitutes for bivalent oxygen to give a greater degree of cross-linking in the glass network. The improved properties afforded by nitrogen substitution may lead to commercial applications for oxynitride glasses as hardened windows, high modulus glass fibers, leach-resistant coatings, and as joining compositions for nitrogen ceramics.
