Analysis on Relationship between the Composition and Properties of Glaze Based on the Phase Diagram Theory
Based on the CaO-Al2O3-SiO2 ternary phase diagram,four glazes,namely transparent glaze,crystalline glaze,emulsion glaze and matte glaze,are prepared in the four crystallization regions in the triangular region of SiO2,CaO·SiO2,CaO·A12O3·2SiO2 respectively.Through the observation and analysis of the final product of the glazes and the analysis and discussions on the four crystallization regions of the phase diagram,it has revealed the relationship between the chemical compo-sition and properties of each glaze type and the change law between each glaze types.
