Preparation method of CaLa2S4 infrared transparent ceramic through high-energy ball milling and SPS sintering
The invention relates to the technical field of new material preparation, in particular to a preparation method of high-energy ball milling and spark plasma sintering (SPS) sintered CaLa2S4 infrared transparent ceramic. The method comprises the following steps: (1) mixing CaS and La2S3 powder according to a certain proportion under the protection of inert gas, and then carrying out high-energy ball milling to obtain CaLa2S4 powder; (2) wrapping the obtained CaLa2S4 powder with graphite paper, and then carrying out spark plasma sintering in a vacuum state; (3) after sintering, polishing the obtained block CaLa2S4 ceramic to obtain the CaLa2S4 infrared transparent ceramic. According to the preparation method disclosed by the invention, ceramic forming is realized by utilizing high-energy ball milling and spark plasma sintering, and the CaLa2S4 infrared transparent ceramic with high hardness, high transmittance and high corrosion resistance is prepared.
