Dental ceramics An update ncbim.nih.gov

A ceramic core is formed onto a refractory die from a fine slurry of alumina powder by a process known as slip casting. After the die has dried, it is sintered for 10 h at 1120C. The melting temperature of alumina is too high to produce full densification of the powder by liquid phase sintering, and solid phase sintering alone occurs.

Sintering is a diffusional process that proceeds at relatively high temperatures, usually between 1/2 and 3/4 of the melting temperature of the ceramic.2 During sintering, material is transported to inter-particle necks to build a strong ceramic bond. The goal of the sintering step is to convert a porous powder compact into a useful part.
