99 alumina structural ceramic and preparation method thereof
The invention provides 99 aluminum oxide structural ceramic, which solves the problems that the performance of a ceramic product is reduced and the cost is high due to high-temperature sintering, and the loss of a kiln and kiln furniture is relatively large. The 99 aluminum oxide structural ceramic comprises the following raw materials: aluminum oxide, magnesium oxide, silicon oxide and rare earth oxide. The aluminum oxide comprises flaky aluminum oxide, and based on the total mass of the 99 aluminum oxide structural ceramic raw material, the content of the flaky aluminum oxide is greater than 0 and less than or equal to 20%. Through cooperation of the 99 alumina structural ceramic raw materials, the sintering temperature is reduced, so that the cost is reduced, and the loss of a kiln and kiln furniture is reduced; and the obtained 99 alumina structure ceramic product has high fracture toughness and strength.
本申请提供了一种99氧化铝结构陶瓷，解决了高温烧结导致的陶瓷产品性能下降、成本高、以及窑炉和窑具损耗较大的问题。99氧化铝结构陶瓷包括以下原料：氧化铝、氧化镁、氧化硅和稀土氧化物；氧化铝包括片状氧化铝，且基于99氧化铝结构陶瓷原料的总质量，片状氧化铝的含量为大于0且小于等于20％。以上99氧化铝结构陶瓷原料之间的配合利于降低烧结温度以降低成本、降低对窑炉和窑具的损耗；且获得的99氧化铝结构陶瓷产品的断裂韧性和强度较高。
