Magnesium fluoride optical ceramic as well as preparation method and application thereof
The invention relates to the technical field of infrared optical devices, and discloses magnesium fluoride optical ceramic as well as a preparation method and application thereof. The method comprises the following steps: (1) screening magnesium fluoride to obtain magnesium fluoride powder with the average particle size of 10-100mm; (2) subjecting the magnesium fluoride powder to pre-pressing treatment, and obtaining a pre-pressed part; and (3) under the vacuum condition, subjecting the pre-pressed part to sintering treatment, wherein the pressure of sintering treatment ranges from 200 MPa to 400 MPa, the temperature ranges from 700 DEG C to 1000 DEG C, and the vacuum degree ranges from 1 Pa to 50 Pa. The magnesium fluoride optical ceramic prepared by the method is high in density and purity, has excellent mechanical properties such as high hardness, high transmittance, compression strength and bending strength, and can effectively reduce refraction and reflection loss when being applied to infrared optical devices.
本发明涉及红外光学器件技术领域，公开了一种氟化镁光学陶瓷及其制备方法和应用。该方法包括：（1）将氟化镁进行筛选，得到平均粒径为10‑100mm的氟化镁粉末；（2）将所述氟化镁粉末进行预压处理，得到预压件；（3）在真空条件下，将所述预压件进行烧结处理，其中，所述烧结处理的压力为200‑400MPa，温度为700‑1000℃，真空度为1‑50Pa。采用本发明方法制备得到的氟化镁光学陶瓷致密度和纯度高，且具有高硬度、高透过率、压缩强度和弯曲强度等机械性能优异，将该氟化镁光学陶瓷应用于红外光学器件中，能够有效降低折射和反射损失。
