Minimization of water absorption and pyroplastic deformation of wollastonite-containing alumina-strengthened porcelain

The densification and pyroplastic deformation of alumina-strengthened porcelain were examined within a range of alumina and wollastonite contents. Both the alumina addition and anorthite crystallization not only prevent the liquid-phase sintering, which plays an important role in the densification o...
