Application Characteristics of Andalusite Refractory
The thermal shock properties of andalusite castables are due to the fact that the added andalusite decomposes at high temperatures to form a structure of mullite and silica-rich glass phases. The silica-rich glass phase produced by andalusite fills the pores and enhances the effect of promoting sintering so that the castable structure slows
