Pressureless sintering high-toughness silicon carbide and preparation method thereof
The pressureless sintering high-toughness silicon carbide is prepared from the following raw materials in parts by weight: 96 to 98 parts of silicon carbide, 0.8 to 1.2 parts of boron carbide, 1 to 3parts of graphene, 0.6 to 0.8 part of a dispersing agent, 4 to 6 parts of a binding agent, 5 to 7 parts of phenolic resin, 0.8 to 1.2 parts of a lubricating liquid and 90 to 110 parts of deionized water. The pressureless sintering high-toughness silicon carbide has the beneficial effects that graphene is added into the silicon carbide in the preparation process of the pressureless sintering high-toughness silicon carbide, so that the fracture toughness of a sealing ring of the prepared silicon carbide material is about 20% higher than that of common pressureless sintering silicon carbide; andthe preparation method of the pressureless sintering high-toughness silicon carbide is simple and easy to operate.
本发明公开了一种无压烧结高韧性碳化硅，包括下述重量份的原料：碳化硅96‑98份、碳化硼0.8‑1.2份、石墨烯1‑3份、分散剂0.6‑0.8份、粘结剂4‑6份、酚醛树脂5‑7份、润滑液0.8‑1.2份、去离子水90‑110份。本发明的有益效果为：本发明所述一种无压烧结高韧性碳化硅制备过程中在碳化硅中加入石墨烯，使制得碳化硅材料的密封环断裂韧性比一般的无压烧结碳化硅高20％左右；本发明所述一种无压烧结高韧性碳化硅的制备方法简单、易于操作。
