High-infrared-emissivity perovskite type ceramic material and preparation method and application thereof
The invention discloses a high-infrared-emissivity perovskite type ceramic material and a preparation method and application thereof, the molecular formula of the ceramic material is Sr (Zr1-yXy) Oz, and X is Mg, Ca, Mn, Fe, Co, Ni, Cu or Zn; the preparation method comprises the following steps: adding the water-soluble strontium salt, the water-soluble X salt and the water-soluble zirconium salt into deionized water, heating and dissolving in a water bath to obtain a mixed system A; under the water bath condition, citric acid is added into the mixed system A, stirring is continued, and a mixed system B is obtained; under a water bath condition, dropwise adding ammonia water into the mixed system B, and continuously stirring to obtain a mixed system C; drying and drying the mixed system C, and grinding a dried product obtained after drying to obtain precursor powder; and sintering the precursor powder at normal pressure. According to the invention, the technical problem that the existing SrZrO3 ceramic material has low infrared radiance at the wave band of 1-22 [mu] m between room temperature and 600 DEG C can be solved.
本发明公开一种高红外发射率钙钛矿型陶瓷材料及其制备方法和应用，陶瓷材料的分子式为Sr(Zr1‑yXy)Oz，X为Mg、Ca、Mn、Fe、Co、Ni、Cu或Zn；其制备方法：将水溶性锶盐、水溶性X盐和水溶性锆盐加入去离子水中水浴加热溶解，得到混合体系A；在水浴条件下，向混合体系A中加入柠檬酸继续搅拌，得到混合体系B；在水浴条件下，向混合体系B中逐滴加入氨水继续搅拌，得到混合体系C；将混合体系C烘干和干燥，并将干燥后得到的干燥产物进行研磨，得到前驱体粉末；将前驱体粉末在常压下进行烧结。本发明可以解决现有的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。
