Andalusite is a natural product (alumina-silicate) that is available in the form of polyhedral mineral crystals. This material is widely used in refractory industries, especially when high thermal resistance is required.
This product usage is in its different granulations: in furnaces, high-temperature steel industries, thermal coatings, and also as high-temperature abrasives.
High mechanical and chemical resistance, resistance against thermal shocks, resistance against creep, and resistance against acid corrosion are other features of this product.
The variety of granularity and the availability of this product, along with the advantage of the cost compared to the performance, has made it the best choice for the above industries.
