Ceramic composition, preparation method of cutting-resistant ceramic and cutting-resistant ceramic
The invention provides a ceramic composition, a preparation method of cutting-resistant ceramic and the cutting-resistant ceramic, and belongs to the technical field of ceramic materials. The ceramic composition comprises the following components in percentage by mass: 65-70% of silicon oxide, 20-23% of aluminum oxide, 0.3-0.6% of iron oxide, 2-5% of calcium oxide, 1-3% of magnesium oxide, 2-4% of potassium oxide, 2-4% of sodium oxide and 0.4-0.7% of zirconium oxide. The ceramic composition is subjected to firing treatment, the prepared cutting-resistant ceramic takes a mica phase as a main crystal phase and also contains mullite whiskers and nano-zirconia, and the cutting-resistant ceramic composition formed by in-situ generated mica crystals, mullite whiskers and additional zirconia powder is developed. The strength, toughness and cutting resistance of a ceramic rock plate are remarkably improved, and meanwhile the machining damage rate and the flitch damage rate of the ceramic rock plate are reduced.
本申请提供一种陶瓷组合物、耐切削陶瓷的制备方法及耐切削陶瓷，属于陶瓷材料技术领域。陶瓷组合物其按质量百分比计包括：氧化硅65～70％、氧化铝20～23％、氧化铁0.3～0.6％、氧化钙2～5％、氧化镁1～3％、氧化钾2～4％、氧化钠2～4％以及氧化锆0.4～0.7％。采用该陶瓷组合物进行烧制处理，制备得到的耐切削陶瓷以云母相为主晶相还含有莫来石晶须和纳米氧化锆，开发出一种由原位生成的云母晶体和莫来石晶须及外加氧化锆粉体构成的耐切削陶瓷组合物，显著提高陶瓷岩板强度、韧性和耐切削性能的同时，降低陶瓷岩板的加工破损和贴板破损率。
