Thermal-Shock Resistance
Average coefficient of expansion from 20° C to 200° C is 3.56 x 10-6, gradually increasing to 4.69 x 10-6 at 1000° C. Experience has indicated suitability of particular shapes for specific uses. It remains the responsibility of the user to determine the suitability for use. To prevent thermal stress cracks on porcelain ware, CoorsTek strongly recommends a heating/cooling rate not to exceed 200° C/hour. High-alumina labware temperature change rate should not exceed 150° C/hour
