Silica Mullite Bricks

Silica mullite bricks are used for the transition zone, decomposition zone, cooling zone of a medium and small cement kiln.


Product Details


Description of Silica Mullite Bricks


By adopting high-grade bauxite and SiC as raw material and through special sintering process, silica mullite bricks are characterized by high strength, good performance of abrasion resistance and thermal shock resistance, constant forming protective layer for reducing accretion formation, long application cycle, etc. 


Silica mullite bricks are used for the transition zone, decomposition zone, cooling zone of a medium and small cement kiln.
