Fine-grain pink ZTA ceramic and preparation method thereof
The invention discloses a preparation method of fine-grain pink ZTA ceramic. The preparation method comprises the following steps of: mixing aluminum oxide, yttria-stabilized zirconia, carbonic acid and a chromium source to obtain mixed powder; adding the mixed powder into an alkaline solution containing an anionic dispersant; obtaining a mixture, adding an adhesive into the mixture; ball-millingto obtain ceramic slurries, carrying out spray granulation and drying on the obtained ceramic slurry to obtain ZTA composite powder, carrying out compression molding on the ZTA composite powder to obtain a green body, placing the obtained green body in an air atmosphere, carrying out primary sintering to obtain a primary blank, and carrying out hot isostatic pressing sintering on the primary blankto obtain a ZTA ceramic material, wherein the temperature of the hot isostatic pressing sintering is 20-50 DEG C lower than the temperature of the primary sintering. The fine-grain ZTA ceramic obtained by the preparation method has high hardness, toughness, wear resistance and biocompatibility, and can be widely used as a cutting tool, structural ceramic, a human body wear-resistant implant material and the like.
本发明公开了一种细晶粒粉色ZTA陶瓷的制备方法，将氧化铝、氧化钇稳定氧化锆、碳酸物、铬源混合获得混合粉末，将混合粉末加入至含阴离子型分散剂的碱性溶液中，获得混合料，再于混合料中加入粘接剂，然后球磨，获得陶瓷浆料，所得陶瓷浆料进行喷雾造粒、干燥，获得ZTA复合粉末，再将ZTA复合粉末压制成型即得生坯，所得的生坯置于空气气氛中，进行初烧结，获得初坯，再将初坯进行热等静压烧结，即得ZTA陶瓷材料，热等静压烧结的温度相比初烧结的温度低20～50℃。该制备方法获得的细晶粒ZTA陶瓷具有较高的硬度、强韧性、耐磨性和生物相容性，可广泛应用作切削刀具、结构陶瓷及人体耐磨植入材料等。
