Preparation method of ternary sulfide ceramic powder
The invention relates to the technical field of infrared transparent ceramics, in particular to a preparation method of ternary sulfide ceramic powder. According to the preparation method, in protective gas, a source A, a source B, a source S and grinding balls are mixed and subjected to high-energy ball milling, the ternary sulfide ceramic powder with the chemical composition of AB2S4 is obtained, A in the AB2S4 is alkaline earth metal, and B in the AB2S4 is lanthanide metal; wherein the source A comprises alkaline earth metal simple substances and/or alkaline earth metal sulfides, the source B comprises lanthanide metal simple substances and/or lanthanide metal sulfides, and the source S is one or more of alkaline earth metal sulfides, lanthanide metal sulfides and sulfur simple substances; and the alkaline earth metal elements, lanthanide series metal elements and sulfur elements in the source A, the source B and the source S meet the stoichiometric ratio of the three elements in the ternary sulfide ceramic powder. The preparation method provided by the invention is safe, efficient, simple to operate and low in raw material cost.
本发明涉及红外透明陶瓷技术领域，尤其涉及一种三元硫化物陶瓷粉体的制备方法。本发明提供的制备方法，在保护气体中，将A源、B源、S源和磨球混合高能球磨，得到化学组成为AB2S4的三元硫化物陶瓷粉体，所述AB2S4中的A为碱土金属，B为镧系金属；所述A源包括碱土金属单质和/或碱土金属硫化物，所述B源包括镧系金属单质和/镧系金属硫化物，所述S源为碱土金属硫化物、镧系金属硫化物和硫单质中的一种或多种。所述A源、B源和S源中的碱土金属元素、镧系金属元素和硫元素满足三元硫化物陶瓷粉体中三种元素的化学计量比。本发明提供的制备方法安全高效且操作简单、原料成本低。
