Ceramic powder as well as preparation method and application thereof
The invention discloses ceramic powder as well as a preparation method and application thereof. The ceramic powder comprises amino-modified aluminum oxide, the preparation raw materials of the amino-modified aluminum oxide comprise aluminum oxide and an amine compound; the mass ratio of the amine compound to the aluminum oxide is 1: (0.5-6). According to the ceramic powder disclosed by the invention, aluminum oxide is subjected to surface modification by adopting an amine compound, so that a surface group of the aluminum oxide has an amino functional group, and when the ceramic powder is used for preparing a ceramic structural part, the ceramic powder can be combined with a hydroxyl-containing additive and is subjected to condensation reaction, so that the binding property of the ceramic powder and the additive is enhanced; the feeding stability of the prepared ceramic structural part is enhanced, so that the phenomenon of composition segregation in the injection process is reduced or even avoided, a ceramic structural part green body with uniform density distribution and good shape retention is obtained, the mechanical strength is improved, the ceramic structural part with high quality and long service life is obtained, and the quality and the yield of a finished product of the ceramic structural part are improved.
本发明公开了一种陶瓷粉体及其制备方法和应用，所述陶瓷粉体包括氨基改性的氧化铝；所述氨基改性的氧化铝的制备原料包括氧化铝和胺类化合物；所述胺类化合物和氧化铝的质量比为1：(0.5～6)。本发明中的陶瓷粉体采用胺类化合物对氧化铝进行表面改性，使其表面基团带有氨基官能团，将该陶瓷粉体用于制备陶瓷结构件时，可以与含羟基的添加剂结合并发生缩合反应，从而增强陶瓷粉体与添加剂的结合性，增强制得的陶瓷结构件喂料的稳定性，从而减少甚至避免注射过程中成分偏析现象的出现，获得密度分布均匀、保型性好的陶瓷结构件生坯，机械强度提升进而获得高质量、使用寿命长的陶瓷结构件，提高陶瓷结构件成品的质量和成品率。
