Ultrahigh-temperature antioxidant nano composite ceramic
The invention relates to the technical field of ceramic production, in particular to ultrahigh-temperature antioxidant nano composite ceramic. The composite ceramic comprises the following raw materials in parts by weight: 15-25 parts of phenolic resin, 17-23 parts of diboron trioxide, 34-46 parts of silicon dioxide, 17-23 parts of zirconium dioxide, 10-15 parts of boron nitride, 10-15 parts of aluminum nitride, 20-30 parts of absolute ethyl alcohol, 80-100 parts of organic silane, 0.6-0.9 part of a sintering aid, 0.7-0.9 part of polyethylene glycol, 0.8-1.2 parts of a modified blank enhancer and 0.7-0.9 part of a scratch-resistant agent. The preparation method comprises the following steps: S1, weighing raw materials, ball-milling and mixing boron nitride, aluminum nitride, absolute ethyl alcohol and organic silane for 4-6 hours to obtain ball-milled slurry; according to the invention, the compressive strength of the ceramic can be effectively improved, and the scratch resistance of the ceramic is also enhanced.
本发明涉及陶瓷生产技术领域，尤其涉及一种超高温抗氧化纳米复合陶瓷，该复合陶瓷按重量份计包括以下原料：酚醛树脂15～25份、三氧化二硼17～23份、二氧化硅34～46份、二氧化锆17～23份、氮化硼10～15份、氮化铝10～15份、无水乙醇20～30份、有机硅烷80～100份、烧结助剂0.6～0.9份、聚乙二醇0.7～0.9份、改性胚体增强剂0.8～1.2份和抗划伤剂0.7～0.9份，且其制备方法包括以下步骤：S1、按量称取原料，并将氮化硼、氮化铝、无水乙醇和有机硅烷球磨混合4～6h，得球磨浆料。本发明不仅能够有效地提高陶瓷的抗压强度，而且还能改善陶瓷的耐划伤性能。
