高温烧结条件下蓝晶石的莫来石化
Mullitization of Cyanite at High Sintering Temperature
【摘要】 采用两种不同粒度的蓝晶石为主要原料,加入不同数量的轻烧高铝矾土,并分别于1600℃和1650℃下烧结,研究讨论所得试样的烧结性能。试验结果表明:提高铝硅比可以降低莫来石形成的起始温度;适当提高合成温度,可使莫来石含量提高,气孔率降低,体积密度增加。
【Abstract】 The sintering performance of the samples composed of two different sizes cyanite and different amount of bauxite has been investigated at 1600℃ and 1650℃.The test results showed that the starting temperature of forming mullite can be decreased by increasing Al/Si ratio. Moderately increasing sintering temperature can increase content of mullite and bulk density,and also decrease porosity.
