Product Detail

As a packing elements ,Mullite Block are superior in better thermal shock resistance , higher AL content , good crack resistance and lower coefficient of heat expansion comparing with alumina and dense alumina material, which has been widely used in thermal treatment of RTO equipments among industrial fields.

Ceramic accumulators especially Mullite ceramic material blocks shaped with straight through, square channels are preferred to be used in aggressive media due to the high chemical resistance and thermal stability.
