The invention relates to the technical field of ceramic forming, and discloses a method for preparing an AlON ceramic green body through injection molding, and the method comprises the following steps: S1, dispersing an isobutylene-maleic anhydride copolymer and a tetramethylammonium hydroxide aqueous solution in deionized water, and carrying out ultrasonic dispersion to prepare a premixed solution; s2, adding AlON powder into the premixed liquid, and stirring to obtain AlON ceramic slurry with the solid content of 45 vol%; s3, the AlON ceramic slurry is injected into a mold after being subjected to vacuum defoaming treatment, an AlON ceramic wet blank is obtained after solidification, drying is conducted after demolding, and an AlON ceramic green body is obtained. The isobutylene-maleic anhydride copolymer and the TMAH are used as dispersing agents, the dispersity and the fluidity of the slurry are improved, an AlON green body is prepared through injection molding, and the uniformity of the green body is improved.
本发明涉及陶瓷成型技术领域，公开了一种注模成型制备AlON陶瓷坯体的方法，包括如下步骤：S1、将异丁烯‑马来酸酐共聚物和四甲基氢氧化铵水溶液分散在去离子水中超声分散后配置成预混液；S2、向预混液中加入AlON粉体，搅拌后得到固含量45vol％的AlON陶瓷浆料；S3、AlON陶瓷浆料经真空脱泡处理后注入模具中，发生凝固得到AlON陶瓷湿坯，脱模后烘干，得到AlON陶瓷坯体。利用异丁烯‑马来酸酐共聚物和TMAH作为分散剂，提高浆料的分散性、流动性，注模成型制备AlON坯体，提高了坯体的均匀性。
