Preparation method and application of high-temperature high-infrared-emissivity ceramic material
The invention discloses a preparation method and application of a high-temperature and high-infrared-emissivity ceramic material, and the preparation method comprises the following steps: mixing a strontium source, a metal X source and a zirconium source to obtain mixed raw material powder; putting the mixed raw material powder into a ball-milling tank, adding absolute ethyl alcohol and a ball-milling medium, and performing ball-milling to obtain mixed slurry A after the ball-milling is finished; drying the mixed slurry A, and fully grinding to obtain slurry powder B; pre-sintering the slurry powder B at normal pressure to obtain pre-sintered powder C after sintering is finished; placing the pre-sintered powder C in a ball milling tank, adding absolute ethyl alcohol and a ball milling medium for ball milling, and obtaining mixed slurry D after ball milling is finished; drying the mixed slurry D, and fully grinding to obtain slurry powder E; and sintering the slurry powder E at normal pressure. The material can be used for radiation heat dissipation of high-power optical and electronic devices. According to the invention, the technical problem that the infrared radiance of the SrZrO3 ceramic material at the wave band of 1-22 [mu] m between room temperature and 600 DEG C is low can be solved.
本发明公开一种高温高红外发射率陶瓷材料的制备方法及应用，制备方法：将锶源、金属X源和锆源混合，得到混合原料粉末；将混合原料粉末置于球磨罐中，加入无水乙醇和球磨介质后进行球磨，球磨结束后得到混合浆料A；将混合浆料A干燥后充分研磨，得到浆料粉末B；将浆料粉末B进行常压预烧结，烧结结束后得到预烧结粉末C；将预烧结粉末C置于球磨罐中，加入无水乙醇和球磨介质进行球磨，球磨结束后得到混合浆料D；将混合浆料D干燥后充分研磨，得到浆料粉末E；将浆料粉末E进行常压烧结，该材料可用于大功率光学和电子器件的辐射散热。本发明可以解决SrZrO3陶瓷材料在室温到600℃之间1～22μm波段的红外辐射率较低的技术问题。
