Silicon carbide ceramic product and preparation method thereof
The invention discloses a silicon carbide ceramic product and a preparation method thereof, and relates to the field of ceramic materials, the silicon carbide ceramic product comprises an aggregate, a powder material and a binder, the aggregate and the powder material are prepared according to a weight ratio of the aggregate to the powder material being 55-65: 35-45; the aggregate is silicon carbide particles; the powder materials are cordierite fine powder, aluminum oxide fine powder and metal aluminum powder; the weight ratio of the cordierite fine powder to the aluminum oxide fine powder to the metal aluminum powder is 70-80: 20-30: 2-5; the binder is any one or a combination of two of water-soluble epoxy resin, water-soluble phenolic resin and water-soluble furan resin, and the addition amount of the binder is 2-4% of the total weight of the aggregate and the powder; the silicon carbide ceramic product is prepared through the steps of raw material proportioning, slurry preparation, forming and high-temperature firing. The prepared silicon carbide ceramic product has excellent high-temperature performance of silicon carbide and excellent thermal shock resistance, and the service life of the silicon carbide kiln furniture product can be effectively prolonged.
一种碳化硅陶瓷制品及其制备方法，涉及陶瓷材料领域，包括骨料、粉料和结合剂，骨料与粉料按下述重量份配置而成：骨料与粉料的重量配比为：骨料∶粉料=55～65∶35～45；骨料为碳化硅颗粒；粉料为堇青石细粉、氧化铝细粉和金属铝粉；粉料的重量配比为：堇青石细粉∶氧化铝细粉：金属铝粉=70~80∶20~30∶2~5；结合剂为水溶性环氧树脂、水溶性酚醛树脂、水溶性呋喃树脂中的任意一种或两种组合，结合剂的加入量为骨料、粉料总重量的2～4%；通过原料配比、浆料制备、成型和高温烧成步骤制备而成；本发明所制备的陶瓷制品既具有碳化硅优良的高温性能，同时也具有非常优良的热震稳定性，能够有效地提高碳化硅窑具制品的使用寿命。
