Ceramic powder material as well as preparation method and application thereof
The invention discloses a ceramic powder material as well as a preparation method and application thereof, the ceramic powder material is prepared by taking Si3N4 powder as a main raw material, adding an auxiliary material SiC powder, taking Li2C2O4 powder, MgSiN2 powder, BaCO3 powder and YF3 powder as sintering aids, adding all the raw materials and a liquid-phase medium into a ball mill, mixing, and carrying out spray granulation, so as to obtain the ceramic powder material. The ceramic powder material is subjected to high-pressure densification molding and high-temperature sintering in a nitrogen atmosphere, and the silicon nitride ceramic material with high thermal conductivity and mechanical strength can be obtained.
本发明公开一种陶瓷粉体材料及其制备方法与应用，所述陶瓷粉体材料以Si3N4粉末作为主要原料，加入辅料SiC粉末，以Li2C2O4粉末，MgSiN2粉末，BaCO3粉末和YF3粉末作为烧结助剂，将各原料和液相介质加入到球磨机中混合，喷雾造粒，得到本发明的陶瓷粉体材料；将本发明的陶瓷粉体材料进行高压致密化成型、氮气气氛下高温烧结，可得高热导率和机械强度的氮化硅陶瓷材料。
