Preparation method of rare earth silicate ceramic
The invention discloses a rare earth silicate ceramic preparation method, which specifically comprises: S1, mixing raw material powder of a rare earth glass ceramic block, carrying out wet ball milling to obtain a mixed slurry, drying the mixed slurry to obtain a mixed powder, heating the mixed powder, and carrying out high temperature thermal insulation treatment to obtain the rare earth glass ceramic block; s2, performing wet ball milling on the rare earth microcrystalline glass block to obtain slurry, drying the slurry, and sieving to obtain rare earth microcrystalline glass powder; s3, mixing the rare earth microcrystalline glass powder with rare earth oxide, performing wet ball milling to obtain rare earth silicate ceramic slurry, drying the slurry, pressing the slurry into rare earth silicate ceramic blocks, heating, and performing high-temperature heat preservation treatment to obtain the rare earth silicate ceramic. According to the invention, the preparation of the rare-earth silicate ceramic by adopting the rare-earth oxide and the rare-earth microcrystalline glass is proposed for the first time, and a new idea is provided for the preparation of the rare-earth silicate ceramic and the conversion of the rare-earth microcrystalline glass to ceramization.
本发明公开了一种稀土硅酸盐陶瓷的制备方法，具体包括如下步骤：S1、将稀土微晶玻璃块体的原料粉体混合后湿球磨得到混合浆液，将混合浆液干燥后得到混合粉体，将混合粉体升温后经过高温保温处理得到稀土微晶玻璃块体；S2、将稀土微晶玻璃块体湿球磨后得到浆液，将浆液干燥后过筛得到稀土微晶玻璃粉体；S3、将稀土微晶玻璃粉体与稀土氧化物混合后湿球磨得到稀土硅酸盐陶瓷浆液，将浆液干燥后压制成稀土硅酸盐陶瓷块体，升温后经过高温保温处理得到稀土硅酸盐陶瓷，与现有技术相比，本发明首次提出采用稀土氧化物和稀土微晶玻璃实现稀土硅酸盐陶瓷的制备，本发明为稀土硅酸盐陶瓷的制备以及稀土微晶玻璃向陶瓷化的转变提供了新的思路。
