反射炉用兰晶石之炉盖砖的研究

The Research of Disthene Kiln-cover Brick for Reflecting-kiln

研究兰晶石特性表明:兰晶石高温分解不但体积发生膨胀和转化成莫来石,而且分解出来的SiO_2相能和富铝形成更多的莫来石,利用兰晶石这一特性研制开发出优质反射炉不烧制品。

The investgation on characteristic of disthene show that disthene, under gigh temperature, is transformed into mullite and SiO2 which AL2O3 and the expansion of volume occur. According to the character of disthene, premium unfired refractory brick for reflecting kiln were made.
