Rare earth oxysulfide ceramic and preparation method thereof
The invention provides a rare earth oxysulfide ceramic and a preparation method thereof, and relates to the technical field of oxysulfide ceramics. The preparation method of the rare earth oxysulfide ceramic provided by the invention comprises the following steps: S1, ball-milling and mixing an organic solvent, a dispersing agent, rare earth oxysulfide powder, a binder and a plasticizer to obtain slurry; s2, the slurry is injected into a mold, a magnetic field is applied while the slurry is injected, and a primary blank is obtained through curing, demolding and drying; s3, the initial blank is subjected to debonding and sintering, and the rare earth oxysulfide ceramic is obtained. A magnetic field is applied while grouting, and under the action of the magnetic field, grains in rare earth oxysulfide slurry rotate and are directionally arranged along the direction of the magnetic field, so that the microcosmic grain structure of the rare earth oxysulfide ceramic is textured, the birefringence and scattering phenomena of the ceramic grain boundary are reduced, and the transmittance of the material is improved; and an effective way is provided for solving the problem of low transmittance of the rare earth oxysulfide ceramic material.
本发明提供了一种稀土硫氧化物陶瓷及其制备方法，涉及硫氧化物陶瓷技术领域。本发明提供的稀土硫氧化物陶瓷的制备方法，包括：S1、有机溶剂、分散剂、稀土硫氧化物粉体、粘结剂和塑性剂经球磨混合，得到浆料；S2、浆料注入模具中，并在注入浆料的同时施加磁场，经固化、脱模、干燥，得到初坯；S3、初坯经脱粘、烧结，得到稀土硫氧化物陶瓷。通过在注浆的同时施加磁场，在磁场的作用下，稀土硫氧化物浆料中的晶粒沿磁场方向发生旋转和定向排列，使稀土硫氧化物陶瓷的微观晶粒结构织构化，进而降低陶瓷晶界的双折射、散射现象，从而提高材料的透过率，为解决稀土硫氧化物陶瓷材料透过率低的问题提供了一条有效途径。
