Silicon Nitride Block Description
Our silicon nitride blocks are precision-engineered using high-purity raw materials and advanced sintering technology, featuring exceptional hardness and wear resistance (Vickers hardness 1400-1600) while maintaining outstanding mechanical strength and dimensional stability under high-temperature environments. With thermal shock resistance exceeding 800°C temperature differentials, they demonstrate remarkable corrosion resistance against most acids, alkalis, and molten metals. The blocks exhibit uniform density (3.2-3.3 g/cm³) and can achieve mirror-grade surface finish (Ra<0.2μm) through precision machining, coupled with excellent electrical insulation (dielectric strength >15 kV/mm) and low thermal expansion coefficient. Ideal for high-end industrial applications including semiconductor manufacturing equipment components, precision bearing rolling elements, high-speed cutting tools, and turbine engine thermal components, these blocks serve as critical core materials for enhancing equipment performance and operational reliability.
