How to Determine Clay Shrinkage and Make a Shrink Rule

SpletCompaction of ceramic powders is a forming technique for ceramics in which granular ceramic materials are made cohesive through mechanical densification, either by hot or cold pressing. The resulting green part must later be sintered in a kiln. The compaction process permits an efficient production of parts to close tolerances with low drying … Spletbulk ceramics, but the process is not unique to ceramics. There is a large ﬁeld known as “powder metallurgy” that considers many of the concepts and problems that we address for ceramics. One of the reasons for processing metals by sintering is to control the grain size, which is precisely what we usually need to do in ceramics. SpletWater in Ceramics Water is the most important ceramic material, it is present every body, glaze or engobe and either the enabler or a participant in almost every ceramic process and phenomena.
