Ceramic composition, silicon nitride ceramic material, preparation method thereof and ceramic product
The invention relates to a ceramic composition, a silicon nitride ceramic material, a preparation method thereof and a ceramic product, and the ceramic composition comprises the following components in parts by mass: 1-10 parts of boron nitride; 1-8 parts of yttrium oxide; 1-8 parts of aluminum titanate; and 75-95 parts of silicon nitride. The ceramic composition comprises boron nitride, yttrium oxide, aluminum titanate and silicon nitride in a specific proportion, can be black after being sintered, is pure in black and small in color difference, and ensures that the performance of a ceramic product is basically not affected.
本发明涉及一种陶瓷组合物、氮化硅陶瓷材料及其制备方法和陶瓷制品，该陶瓷组合物按质量份数计，包括以下组分：氮化硼1～10份；氧化钇1～8份；钛酸铝1～8份；以及氮化硅75～95份。该陶瓷组合物，包括特定比例的氮化硼、氧化钇、钛酸铝和氮化硅，能在烧结后呈黑色，且黑色纯正，色差较小，且保证陶瓷制品的性能基本不受影响。
