Tetravalent zirconium ion doped yttrium tantalate high-temperature luminescent ceramic and preparation method thereof
The invention discloses a preparation method of tetravalent zirconium ion doped yttrium tantalate high-temperature luminescent ceramic, and belongs to the technical field of high-temperature ceramic preparation. The structural formula of the Zr < 4 + > ion doped yttrium tantalate high-temperature ceramic is (ZrO2) x-(YTaO4) 1-x (x = 0.1, 0.2, 0.3, 0.4, 0.5), the preparation method comprises the following steps: weighing zirconium oxychloride octahydrate, yttrium nitrate hexahydrate, potassium carbonate and tantalum oxide materials according to a chemical formula (ZrO2) x-(YTaO4) 1-x in proportion; the preparation method comprises the following steps: reacting tantalum oxide with potassium carbonate to generate potassium tantalate, respectively dissolving all materials, adding ammonia water to generate hydroxide precipitates, respectively firing to generate oxides, fully mixing all oxides, and firing to obtain the tetravalent zirconium ion doped yttrium tantalate high-temperature luminescent ceramic. The tetravalent zirconium ion doped yttrium tantalate high-temperature luminescent ceramic prepared by the method is small in particle size, reaction conditions are easy to control, the prepared nano material is good in stability and has good luminescent performance, and possibility is provided for real-time monitoring of a thermal barrier coating.
