Method for preparing transparent ceramic through one-time forming based on photocuring 3D printing technology
The invention discloses a method for preparing transparent ceramic through one-time forming based on a photocuring 3D printing technology. The method comprises the following steps: providing an oxide ceramic powder raw material; providing photosensitive resin, a photoinitiator, a dispersing agent, a sintering aid and grinding balls; putting the oxide ceramic powder raw material, photosensitive resin, a photoinitiator, a dispersing agent, a sintering aid and grinding balls into a ball milling tank, carrying out ball milling and mixing to obtain photosensitive ceramic slurry, and carrying out stirring and ball milling on the photosensitive ceramic slurry to increase the solid phase content of the photosensitive ceramic slurry to more than 55 vol%; providing photocuring 3D printing forming equipment; spraying and cleaning the surface of the biscuit by using the alcohol and pure water; carrying out glue removal on the biscuit; and sintering the degreased green body in a vacuum atmosphere at a high temperature, and annealing to obtain the unpolished transparent ceramic component. According to the method, the high-transmittance transparent ceramic can be directly obtained through vacuum sintering, and isostatic pressing treatment is not needed.
基于光固化3D打印技术一次成型制备透明陶瓷的方法，其包括如下步骤：提供氧化物陶瓷粉体原料；提供光敏树脂、光引发剂、分散剂、烧结助剂，以及磨球；将所述氧化物陶瓷粉体原料，以及光敏树脂、光引发剂、分散剂、烧结助剂和磨球放入球磨罐中进行球磨混合以得到光敏陶瓷浆料，经过搅拌球磨所述光敏陶瓷浆料的固相含量提升到55vol％以上；提供光固化3D打印成型设备；使用该酒精与纯水喷淋清洗所述素坯表面；对素坯进行排胶；将所述脱脂坯体置于真空气氛中高温烧结、退火以得到未抛光的透明陶瓷构件。本方法可直接真空烧结得到高透过率的透明陶瓷，无需等静压处理。
