High-strength thermal shock-resistant oxidation-resistant SiC/O'-Sialon composite ceramic and preparation method thereof
The invention discloses high-strength thermal shock-resistant oxidation-resistant SiC/O'-Sialon composite ceramic and a preparation method thereof. The SiC/O'-Sialon composite ceramic is prepared fromthe following raw materials in percentage by mass: 40 percent of SiC powder, 30 percent of alpha-Si3N4 powder, 10 percent of quartz powder, 5 to 10 percent of alpha-Al2O3 powder, 3 to 5 percent of Y2O3 powder, 2 to 4 percent of Sm2O3 powder and 1 to 10 percent of ZrO2 powder, and an adhesive is added into the raw materials and accounts for 5 to 10 percent of the mass of the raw materials. The prepared ceramic material is excellent in high-temperature resistance and oxidation resistance and good in thermal shock resistance, and the service life of a heat absorption system is effectively prolonged.
一种高强抗热震抗氧化SiC/O’‑Sialon复相陶瓷及其制备方法，制备所述复相陶瓷的原料及各原料所占质量百分数为：SiC粉40％、α‑Si3N4粉30％、石英粉10％、α‑Al2O3粉5～10％、Y2O3粉3～5％、Sm2O3粉2～4％、ZrO2粉1～10％，原料中加入粘结剂，所述粘结剂的质量为原料的5～10％。本发明制备的陶瓷材料的抗高温性能、抗氧化性能优良，抗热震性好，有效延长吸热系统的使用寿命。
