Mullite Castable Introduction
Mullite castable is a kind of refractory castable can be directly exposed to flame for the use of refractoriness working lining to achieve high temperature energy saving. Mullite castable is made of high-quality porous mullite aggregate as refractory raw materials, plus fine powder and additives into the mixture. Refractory mullite castable has the characteristics of low thermal conductivity and good insulation properties.
