Effect of ZrO₂ Additive on Phase Composition of CaO-ZrO₂-SiO₂ Glaze

Abstract:

The effect of ZrO₂ content on phase composition of CaO-ZrO₂-SiO₂ glass system was investigated in the present research. CaO, ZrO₂ and SiO₂ were used to made frits. It was found that glass samples of high ZrO₂ content contained wollastonite, pseudowollastonite and Ca₂ZrSi₄O₁₂ as the major components of crystalline phase and samples of low ZrO₂ content mainly included non-crystalline phase. The present results also confirmed that firing temperature and soaking time have influence on the phase transition of wollastonite. At high temperature, the wollastonite phase was changed to the pseudowollastonite phase which was verified by thermal analysis. Microstructure observations of glaze samples revealed the formation of crystals in different directions. The thermal expansion mismatch between glaze and body led to the development of microcracks.
