Abrasive Resistant Super Hard Material
These materials are generally available in granular form, the particles are cemented together using frits to produce abrasive products. However powdered and slurried forms of these materials can also be formed and fired by various means to produce hard materials.
Many of these materials are not used in traditional ceramics but they have such incredible properties that some have been included in this database.

The deflocculation process is the magic behind the ceramic casting process. It enables you to make a slurry of far lower water content and thus lower shrinkage.
A method of forming ceramics where a deflocculated (low water content) slurry is poured into absorbent plaster molds, forming a layer against mold walls, then poured out.
