High-strength ceramic clay and preparation method thereof
The invention relates to the technical field of ceramic clay materials, in particular to high-strength ceramic clay and a preparation method thereof.Polycarbosilane and boron carbide are blended and then sintered, so that a multiphase ceramic component formed after sintering has the characteristics of high oxidation resistance and high acid and alkali resistance of boron carbide; through blending of polycarbosilane, the defects that boron carbide is low in relative density and difficult to sinter are overcome, so that the composite ceramic component also has relatively good toughness on the basis of high hardness and wear resistance, and the ceramic sintered by taking the composite ceramic component as the raw material can have better mechanical properties; the surface modified nano zirconia, the nano alumina and the self-made mullite powder are compounded, the strength of the prepared ceramic clay can be improved to a certain extent, the carbon fibers are added to enhance the performance, and the prepared ceramic clay can have good mechanical properties and impact resistance; therefore, the prepared high-strength ceramic clay has a better market application prospect.
本发明涉及陶瓷土材料技术领域，具体涉及一种高强度的陶瓷土及其制备方法，本发明将聚碳硅烷和碳化硼共混后进行烧结，能够使烧结后形成的复相陶瓷组分具有碳化硼强抗氧化性和强耐酸碱性的特点，并且通过聚碳硅烷的共混改善碳化硼相对密度低和难烧结的缺点，使复相陶瓷组分在具有高硬度和耐磨性的基础上还具有较好的韧性，从而以复相陶瓷组分为原料烧结的陶瓷能够具有更好的力学性能；本发明将表面改性纳米氧化锆、纳米氧化铝和自制莫来石粉末进行复合，能够在一定程度上提高制备的陶瓷土的强度，加入碳纤维进行增强性能，能够使高制备的陶瓷土具有较好的力学性能和抗冲击性能，从而使本发明制备的高强度的陶瓷土具有更好的市场应用前景。
