Heat Shock Resistance
The heat resistant properties of Fine Ceramics are measured by the temperatures at which they begin to melt, and by their levels of thermal shock resistance. Thermal shock resistance refers to a material's ability to withstand rapid changes in temperature. Silicon nitride, a particularly heat tolerant material, displays superior resistance to thermal shock, as tested by heating the material to 550℃ (1,022℉) and then rapidly cooling it by dropping it into water. Silicon nitride is thus suitable for applications involving extreme temperature variations, and in high-temperature industries such as metal manufacturing and energy generation.
