Rheology for Ceramists
Author: Dennis R. DingerPublisher: Lulu.com
ISBN: 0557814057
Category : Technology & Engineering
Languages : en
Pages : 199
Book Description
This book was written to help ceramists to understand the subject of rheology as it applies to suspensions. Topics discussed include viscosity and rheology fundamentals, syneresis and dilatancy and their causes and effects in ceramic process systems, the rheological effects of gelation, flocculation, and deflocculation, as well as the different types of viscometers that can be used to measure rheological properties. Many practical considerations are included throughout this book. The discussion in the final chapter covers the methods available to adjust and control suspension rheologies in the ceramic process environment. This book will be valuable reading and a handy reference for all ceramists, including students, technicians, engineers, managers, and artists, who want to learn more about the rheology of suspensions.
Rheology of Filled Polymer Systems

Book Description
Polymerie materials have been replacing other conventional materials like metals, glass and wood in a number of applications. The use of various types of fillers incorporated into the polymer has become quite common as a means of reducing cost and to impart certain desirable mechanieal, thermal, electrieal and magnetic properties to the polymers. Oue to the energy crisis and high priees of petrochemieals, there has been a greater demand to use more and more fillers to cheapen the polymerie materials while maintaining and/or improving their properties. The advantages that filled polymer systems have to offer are normally offset to some extent by the increased complexity in the rheological behavior that is introduced by the inclusion of the fillers. Usually when the use of fillers is considered, a compromise has to be made between the improved mechanieal properties in the solid state, the increased difficulty in melt processing, the problem of achieving uniform dispersion of the filler in the polymer matrix and the economics of the process due to the added step of compounding. It has been recognized that addition of filler to the polymer brings a change in processing behavior. The presence of the filler increases the melt viscosity leading to increases in the pressure drop across the die but gives rise to less die swell due to decreased melt elasticity.

Effect of Surface Forces on the Rheology of Particle-Liquid Systems and the Consolidation of Ceramic Powders

Pages : 58
Book Description
More reliable ceramics require improved processing reliability. Heterogeneities bought with powders and those inadvertently introduced during processing as well as non-uniform and undefined phase distributions contribute to unreliable processing. Colloidal powder treatments can eliminate many heterogeneities and ensure more uniform phase distributions. To ensure that new heterogeneities are not introduced, colloidally treated powders must be piped, as slurries, directly to a die cavity. Slurry consolidation methods based on particle partitioning, e.g., pressure filtration and centrifugation are emphasized in this review. Interparticle potentials play a dominant role in governing the slurry viscosity, maximum particle packing density and the rheology of the consolidated body. These roles will be reviewed with the objective to understand how damage free bodies can be consolidated from slurries to increase the structural reliability of ceramics and their composites.

Influence of Rheology on Deposition Behavior of Ceramic Pastes in Direct Fabrication Systems

Book Description
Rheology and deposition behavior of four commercially available thick-film inks and an aqueous alumina slurry were investigated using two different slurry-based deposition systems. The first of these deposition systems, a Micropen, is a commercially available system designed for the deposition of electronic thick film circuits. The second system, referred to as a Robocaster, is a developmental system designed to build thick or structural parts. Slurry rheology was seen to have a minor effect on deposition behavior and the bead shape when deposited using the Micropen. The deposition behavior was instead dominated by drying rate; too rapid of a drying rate led to excessive clogging of the tip. Slurry rheology had a greater impact on the shape of beads deposited using the Robocaster. Highly viscous slurries yielded initially well-defined beads, whereas beads deposited using fluid slurries spread quickly. In both cases, significant spreading occurred with time. These observations only held for slurries with slow drying rates. It was observed that very fluid slurries produced well-defined beads when the drying rate was suitably high.
