Abstract

The investigation was carried out for the influence of the firing temperature on the properties of the materials obtained on base of the complex highly concentrated ceramic bonding suspension (HCBS) containing various amounts of Al₂O₃ and SiO₂. Three characteristic isothermal temperature intervals were defined for the materials of all compositions: the preferred sintering or shrinkage (900-1200 оC); the preferred mullitization followed by the growth (1200-1400 оC) and the sintering of the mullitized material (1400-1600 оC). The comparative analysis is given for the sintering and mullitization of the materials in the course of non-isothermal heating and isothermal firing. It was established that the considerable sintering and mullitization is beginning to be observed just in the heating up to the desired temperature. Ill. 6. Ref. 9.
