Sintermullit Mottestein

sintered mullite brick is made of synthesized mullite aggregates and finepowder(less 0.088mm), which was mixed at a rate approximately 50/50, aftershaping under heavy load pressing machine, it was fired under a temperature over 1600 C for adesigned period. The products have very excellent performances under high temperature. typical physical properties Bulk density: 2.50g/cm3 Min. Apparent porosity: 18% Max. Cold crushing strength:70MPa Min. Refractoriness under load(0.2 MPa, 0.6%): 1580 C Min.
