Effect of Active Alumina on Sintering Behavior of Andalusite Powder

Abstract:

The effect of active alumina on the sintering behavior of andalusite powder was studied. The results revealed that the addition of active alumina delayed the decomposition of andalusite and primary mullitization, beginning temperature of secondary mullitization was about 1350°C. The temperature at which the effect of expansion of the secondary mullitization emerged was about 1400°C, and the expansion effect of secondary mullitization did not yet complete at 1600°C.
