Influence of Sinter Temperature on the Hardness of Fly Ash Based Glass Ceramics

Article Preview

Abstract:

The glass ceramics bricks were prepared by the method of isostatic pressing and one time sintering using fly ash and glass powder as raw materials. X-ray diffraction experiment was performed to identify the main crystal phase. The influence of sinter temperature on the hardness was studied. It was concluded that the main phase were anorthite and albite. The hardness of sample which contains 60% of fly ash attains 766.79MPa when the sintering temperature was 1110°C .The hardness of sample which contains 50% of fly ash attains 780MPa when the sintering temperature was 1075°C.
