Alumina-glass composites that contain oxidized aluminium were investigated to make shrinkage-free, all-ceramic dental procelain. This was achieved by control of the volume expansion and shrinkage that occur during the aluminium oxidation and densification processes. The dimensional change and strength of the alumina-glass composites were dependent on the aluminum content and particle size.
