摘要：
The effect of colemanite additives on sintering and the properties and microstructure of spodumene ceramic is studied. It is found that to identify the sintering and formation processes of a higher-density structure of ceramic it is most effective to introduce colemanite in the amounts 5 - 7%. Spodumene ceramic with CLTE (9.8 - 12.9) x 10(-7) K-1, heat-tolerance greater than 100 heat cycles (800 degrees C - water), water absorption 0.7 - 5.0%, and mechanical strength under bending 33 - 44 MPa, which all obtain at the sintering temperature 1200 degrees C, was obtained.
