High-temperature-resistant ceramic and preparation method thereof
The invention discloses high-temperature-resistant ceramic and a preparation method thereof. The high-temperature-resistant ceramic is prepared from the following raw materials in parts by weight: spodumene powder, kaolin, silicon dioxide, a silicon carbide mixture, talcum powder, barium carbonate, amorphous silicon dioxide, reinforced fibers, polyethylene wax, aluminum oxide and boron oxide. Theaverage particle size of the amorphous silicon dioxide is 5-15 microns, wherein the particle size of the spodumene powder is 50-100 microns. The prepared high-temperature-resistant ceramic product ishigh in mechanical strength, high in product percent of pass, good in thermal shock resistance, free of defects such as cracks and damage after multiple times of hot and cold circulation, simple in preparation method, easy to operate in preparation process, high in economic benefit and suitable for large-scale popularization.
本发明公开了一种耐高温陶瓷及其制备方法，制备耐高温陶瓷的原料按其重量份包括：锂辉石粉、高岭土、二氧化硅、碳化硅混合料、滑石粉、碳酸钡、无定形二氧化硅、强化纤维、聚乙烯蜡、氧化铝、氧化硼；无定形二氧化硅的平均粒径为5μm～15μm；锂辉石粉的粒径为50μm～100μm。本发明制备的耐高温陶瓷产品的机械强度大，产品合格率高，抗热震性好，经多次冷热循环后产品无裂纹、破损等缺陷，并且制备方法简单，制备工艺易操作，经济效益大，适合大规模推广。
