High-hardness ceramic and preparation method thereof
The invention discloses high-hardness ceramic and a preparation method thereof. The invention discloses high-hardness ceramic, and belongs to the technical field of ceramic materials. The high-hardness ceramic is prepared from, by mass, 30-50 parts of alpha-silicon nitride, 10-30 parts of beta-silicon nitride, 5-10 parts of aluminum oxide, 1-5 parts of zirconium nitride, 3-9 parts of tungsten nitride, 3-7 parts of niobium pentoxide, 1-5 parts of magnesium fluoride, 5-15 parts of silicon carbide, 1-5 parts of boron nitride and 1-3 parts of boron carbide. The high-hardness ceramic material provided by the invention still has high high-temperature mechanical properties and good chemical stability at a high temperature (greater than 1200 DEG C), and also has the characteristics of high density, high temperature resistance, high hardness, high density and high strength.
本发明公开了一种高硬度陶瓷及其制备方法，属于陶瓷材料技术领域，该高硬度陶瓷以质量份计，包括以下组分：α‑氮化硅30‑50份、β‑氮化硅10‑30份、氧化铝5‑10份、氮化锆1‑5份、氮化钨3‑9份、五氧化二铌3‑7份、氟化镁1‑5份、碳化硅5‑15份、氮化硼1‑5份、碳化硼1‑3份；本发明的高硬度陶瓷材料在较高温度(＞1200℃)时仍具有较高的高温力学性能和良好的化学稳定性，还具有高致密度、耐高温、高硬度、高密度、高强度的特点。
