The maximum servicetemperature of the product is 800 deg C; linear shrinkage after 800 deg C X 16 h firing is 0.9percent; the cold crushing strength is 1.56 MPa; the flexural strength at ambient temperature is0.81 MPa; the thermal conductivity at ambient temperature (25 deg C) is 0.056 and 0.128 W/(m centredot K) at 800 deg C. The production cost of such a composite is only 1/3 of that of the normalxonotlite thermal insulators. It can substitute the normal xonotlite thermal insulators on mostoccasions with a similar cost to that of normal perlite products.展开更多
