What is Sillimanite Brick?
As we can know from the name, sillimanite brick is mainly made of high quality sillimanite. Commonly, manufacturers use two methods to produce this brick: high temperature sintering method and casting method.
Combining the research results of Kerui’s R&D department and market feedback, Kerui developed a tunnel kiln for mass production of sillimanite bricks. And this production method has been highly recognized by the local government and peers. Over the years, Kerui sillimanite bricks have received high praise from customers for excellent performance. At present, Kerui high alumina refractories have accumulated a good reputation in the market and achieved huge social and economic benefits.

Improvements of KERUI Sillimanite Refractory Brick
Higher Sintering Temperature
During production, the sillimanite refractory fire brick requires higher sintering temperature. Therefore, this product has more excellent properties. For example, it has better refractoriness, chemical resistance, thermal shock resistance, wear resistance, thermal stability and so on.
More Stable Performance
Due to the excellent raw materials, Kerui sillimanite bricks can still maintain stable performance in the face of severe temperature changes, acid corrosion or other working environments. Accordingly, when customers apply sillimanite bricks in kilns, this product can help customers extend the service life of their kilns.
Main Uses of Sillimanite Bricks
The sillimanite brick has good resistance to chemical corrosion, especially high temperature glass liquid. Therefore, customers often choose this brick in the masonry of glass kiln. It won’t cause pollution when customers use this brick in glass kiln. This brick is suitable for different parts of glass kilns. For example, lining and throat of glass kiln, forming of liquid hole… If you’re looking for an ideal refractory brick for your glass kiln, this brick is a good choice.
Except for glass kiln, Kerui sillimanite brick is an excellent material for other industries. Kerui supports customizing the shape and composition of sillimanite bricks for different parts of the kiln. Customizable types include but are not limited to: trough bricks, flow troughs, rotating tubes, spouts, mixing slurries, refractory slag bricks, door bricks, front arch bricks, rear arch bricks, burner bricks, cover bricks, etc. For more uses, you can visit Kerui Twitter profile.
