Brief Introduction
Andalusite is a kind of high quality high aluminum refractory raw material,which has the characteristics of stable volume at high temperature,chemical corrosion resistance,heat resistance,impact resistance, high hot mechanical strength,wide application range and high economic value of non-metallic mineral materials.
Andalusite has high refractoriness, which can reach up to 1800℃. It is also an excellent raw material for preparing refractory materials.
