Abstract

This study investigated the influence of the concentration of sulfate ions at key technological stages of the synthesis of YAG:Cr ceramic powder on the optical properties of ceramics. The particle size and size distribution, the degree of agglomeration, the specific surface area, and the phase composition of the ceramic powder were evaluated. The variations in the microstructure and optical properties of the YAG:Cr ceramic material were assessed in relation to the amount of sulfate ions used at various stages of the synthesis of ceramic powder. It was demonstrated that the use of 0.200 M and 0.045 M solutions of sulfate ions at the stage of precipitation or washing of the precipitate, respectively, resulted in the superior particle size distribution characteristics and the highest monodispersity of precursor powders and YAG:Cr ceramic powders. Furthermore, it improved the optical properties of YAG:Cr ceramics with a transmittance value exceeding 81.5%.

YAG: CR 陶瓷制造不同阶段的硫酸离子添加剂对光学特性的影响

本研究探讨了合成 YAG:Cr 陶瓷粉关键技术阶段硫酸根离子浓度对陶瓷光学性能的影响。研究评估了陶瓷粉末的粒度和粒度分布、团聚程度、比表面积和相组成。评估了 YAG:Cr 陶瓷材料的微观结构和光学特性的变化与陶瓷粉末合成各阶段所使用的硫酸根离子量的关系。结果表明，在沉淀或沉淀物洗涤阶段分别使用 0.200 M 和 0.045 M 的硫酸根离子溶液，可使前驱体粉末和 YAG:Cr 陶瓷粉末具有更好的粒度分布特性和最高的单分散性。此外，它还改善了 YAG:Cr 陶瓷的光学特性，使其透光率超过 81.5%。
