Study on the Glassy Phase Composition of 95 Al₂O₃ Ceramics

Abstract:

The glassy phase in alumina ceramics is implied for Al₂O₃-SiO₂-CaO. The content of Al₂O3 and CaO can be measured by the common titration method for their total dissolution in 5% HNO₃ and that of SiO₂ can be measured by gravimetric method. Therefore, the glassy phase composition in alumina ceramics can be analysed. The content of each component is measured exactly by both powder method and sheet method.
