Sillimanite Brick

  

    

Product Description:
Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite is the best raw material for the manufacture of high alumina refractories or 55-60% alumina bricks. But its use on large scale is not possible due to its fine grading and high cost.
Our customers can avail from us an extensive assortment of Sillimanite Bricks/Blocks, which comprises alumina. In addition to this, these blocks are widely appreciated for their stability against thermal shocking and refractory properties. Clients can avail these products from us in standard as well as customized forms.
