Ceramic material as well as preparation method and application thereof
The invention belongs to the technical field of thermal barrier coatings, and particularly discloses a ceramic material and a preparation method and application thereof. The preparation method comprises the following steps: mixing and grinding Gd2O3, ZrO2 and MnO2, carrying out compression molding on the ground product, and carrying out high-temperature sintering to obtain the Gd2 (MnxZr1-x) 2O7 ceramic material. According to the invention, MnO2 is doped into Gd2Zr2O7, and crystal lattice vibration and carrier absorption concentration of Gd2Zr2O7 are changed through solid solution and multiphase forming methods, so that the high-temperature infrared emissivity of the material is greatly improved within the wavelength range of 3-5 microns.
本发明属于热障涂层技术领域，具体公开了一种陶瓷材料及其制备方法与应用。本发明将Gd2O3、ZrO2和MnO2混合研磨，然后将研磨产物压制成型，再进行高温烧结，即得Gd2(MnxZr1‑x)2O7陶瓷材料。本发明将MnO2掺杂进Gd2Zr2O7，通过固溶以及形成复相的方法，改变Gd2Zr2O7晶格振动以及载流子吸收浓度，使材料的高温红外发射率在3～5μm波长范围内进行大幅提升。
