A1 Super Sillimanite Specification

Sillimanite

We deal with high quality Sillimanite, with the lowest percentage of impurities. Sillimanite or Aluminium Silicate is used as a raw material for high alumina refractories, which are extensively used in Iron and Steel, petrochemicals, Electrical, Cement, Zinc and Glass Industries.
