SILICON NITRIDE CERAMIC MATERIAL FOR MOBILE PHONE REAR COVER AND PREPARATION METHOD THEREFOR

ZHANG JINGXIAN / DUAN YUSEN / LIU NING / MA RUIXIN / JIANG DONGLIANG

A silicon nitride ceramic material for a mobile phone rear cover and a preparation method therefor. The method comprises: using a mixture of a silicon source, a colorant, and a sintering aid as raw materials, mixing the raw material components, and performing shaping and sintering to obtain the silicon nitride ceramic material. The toughness of the silicon nitride ceramic material can reach more than 12 MPa·m1/2; the thermal conductivity thereof can reach 40 to 70 W/m·K; and a dielectric loss thereof is 10−4.
