  • CALCIUM LANTHANUM SULFIDE NANO-POWDERS, METHOD OF MAKING, AND OPTICALLY TRANSMISSIVE BODY FORMED THEREFROM
    Publication number: 20230219824
    Abstract: A method for producing calcium lanthanum sulfide (CLS) nano powder and optical ceramics formed therefrom. The method includes the steps of mixing a lanthanum precursor and calcium precursor in water to obtain a solution and adding a sulfide precursor to the solution. Upon adding the sulfide precursor, stirring the solution for 5-25 minutes at 55-95° C. to obtain a mixture. The mixture is then introduced into a muffle furnace, preheated at 400-600° C., and the mixture is kept for 15-50 minutes to obtain nano powder. The nano powder can be annealed and subjected to spark plasma sintering to obtain the optical ceramics.
