Injection molding process of large SiAlON ceramic
The invention relates to the technical field of ceramics, in particular to an injection molding process of large SiAlON ceramics, which comprises the following steps: A, preparing ceramic powder; b, feed preparation; c, injection molding; d, solvent degreasing; e, thermal degreasing and pre-sintering; and F, sintering. The large SiAlON ceramic produced by the injection molding process is high in dimensional precision, the dimensional tolerance of a sintered finished product can be controlled to be +/-0.1%, the surface smoothness can reach 3-5 microns, the required machining allowance is extremely small, the cost required by later dimensional precision machining is greatly reduced, the production period is short, and the production efficiency is greatly improved.
本发明涉及陶瓷技术领域，具体涉及一种大型SiAlON陶瓷的注射成型工艺，一种大型SiAlON陶瓷的注射成型工艺，包括以下步骤：A、陶瓷粉体配置；B、喂料制备；C、注射成型；D、溶剂脱脂；E、热脱脂和预烧；F、烧结。该注射成型工艺生产得到的大型SiAlON陶瓷尺寸精度高，烧结后的成品尺寸公差可以控制在±0.1％，表面光洁度可达到3‑5μm，所需加工余量极小，极大地降低了后期尺寸精度加工所需的成本，且生产周期短，极大地提高了生产效率。
