Thermal Shock Resistance
Average coefficient of expansion from 20 degree to 200 degree C is 3.56 x 10-u, gradually increasing to 4.69 x 10-u at 1000 degree C. Experience has indicated suitability of particular shapes for specific uses. lt remains the responsibility of the user to determine the suitability for his use. To prevent thermal stress cracks on porcelain ware, Silico strongly recommends a heating/cooling rate not to exceed 200 degree C/hour. High Alumina labware temperature change rate should not exceed 150 degree C/hour.
