The invention provides a ceramic composition, silicon nitride and a preparation method thereof, and a ceramic product. The ceramic composition is prepared from the following components in parts by mass: 80 to 100 parts of silicon nitride, 1 to 10 parts of a first sintering aid, 1 to 10 parts of a second sintering aid, 0.5 to 20 parts of a dispersing agent, 10 to 40 parts of a binding agent and 0.5 to 2 parts of a de-foaming agent, wherein the first sintering aid is a non-oxidized magnesium-containing compound, and the second sintering aid is a rare earth silicide. When the raw materials comprising the ceramic composition are used for preparing the silicon nitride ceramic, the thermal conductivity and the bending strength of the prepared silicon nitride ceramic can be improved at the same time.
本申请提供一种陶瓷组合物、氮化硅及其制备方法、陶瓷制品。按照质量份数计，所述陶瓷组合物包括：80份~100份氮化硅、1份~10份第一烧结助剂、1份~10份第二烧结助剂、0.5份~20份分散剂、10份~40份粘结剂、0.5份~2份消泡剂；其中，所述第一烧结助剂为非氧化的含镁化合物，所述第二烧结助剂为稀土硅化物。采用包括该陶瓷组合物的原料制备氮化硅陶瓷时，能同时提高制得的氮化硅陶瓷的导热性和抗弯强度。
