Ceramic Material Manufacturing Methods All ceramics start as a mixture of powdered base material (Zirconia, etc.), binders and stabilizers. This mixture is “formed” into shapes and then fired (sintered) at high temperature to create hard, dense materials. Forming is done using standard processes such as pressing, extruding, injection molding, tape casting or slip casting. Ceramics
