3D printing aluminum oxide ceramic material and preparation method
The invention discloses a 3D printing aluminum oxide ceramic material and a preparation method, and belongs to the technical field of additive manufacturing. The aluminum oxide ceramic material comprises the following components in percentage by mass: 2%-5% of a dispersing agent, 1%-5% of a sintering aid, 70%-85% of aluminum oxide powder and the balance of a ceramic precursor, totaling 100%. The solid content of the aluminum oxide powder can reach 70% or above, meanwhile, a polysiloxane ceramic precursor capable of being subjected to photocuring 3D printing is introduced, and after the prepared aluminum oxide ceramic material is sintered, the density of ceramic can reach 99%, the density is higher, and defects are fewer.
本发明公开了一种3D打印氧化铝陶瓷材料及制备方法，属于增材制造技术领域。该氧化铝陶瓷材料以质量百分比包括：分散剂2％～5％，助烧剂1％～5％，氧化铝粉体70％～85％，余量用陶瓷前驱体补至100％。本发明中的氧化铝粉体固含量可达70％及以上，同时引入可光固化3D打印的聚硅氧烷陶瓷前驱体，制得的氧化铝陶瓷材料烧结后陶瓷的致密度可达99％，致密度更高、缺陷更少。
