Tin barium titanate thermal control ceramic as well as preparation method and application thereof
The invention provides tin barium titanate thermal control ceramic and a preparation method and application thereof.The BaTi < 1-x > SnxO3 ceramic is prepared through a solid-phase reaction method, x is larger than or equal to 0.05 and smaller than or equal to 0.15, x is the molar ratio of Sn < 4 + >, and the tin barium titanate ceramic can achieve linearly-adjustable Curie temperature transformation under the doping proportion of Sn 0.05-0.15, and can be used for preparing the tin barium titanate thermal control ceramic. And meanwhile, high reflectivity, namely low solar absorptivity, and high and low temperature variable emissivity are realized in ultraviolet-visible-near infrared bands. Compared with the prior art, the thermally induced phase change material is controllable in phase change temperature, easy to produce on a large scale, capable of improving the integration of a spacecraft space system and reducing the complexity, and capable of being widely applied to thermal control systems of various spacecrafts.
本发明提供了一种锡钛酸钡热控陶瓷及其制备方法、应用，本发明采用固相反应法制备BaTi1‑xSnxO3陶瓷，其中0.05≤x≤0.15，x为Sn4+的摩尔比，该锡钛酸钡陶瓷在Sn0.05‑0.15的掺杂比例下可以实现可线性调节的居里温度的转变，同时在紫外‑可见‑近红外波段实现高反射率即低太阳吸收率，以及高低温的可变发射率。与现有技术相比，该热致相变材料相变温度可控、易于规模化生产、提高航天器空间系统的集成性并降低复杂性，可广泛应用于各种航天器的热控系统。
