| Abstract Scope |
Porcelain containing large amounts of glass has a high tendency to deform at high temperatures, creating problems in the manufacture of the product. Pyroplasticity is related to an excess glass formed during firing and the dissolution of crystal phases.
We have discovered that the addition of appropriate amounts of talc and alumina to porcelain clay causes the formation of cordierite crystals from the excess glass during firing, and we have succeeded in developing non-pyroplastic deformation porcelain during over firing after sintering. The raw material particle size has a significant effect on the dissolution of quartz and alumina and the formation of cordierite crystals. In this study, the effect of raw material particle size on the sintering behavior of the non- pyroplastic deformation porcelain was investigated. Result shows that there was no effect of raw material particle size on pyroplastic deformation and the sintering temperature was reduced by 50°C. |
