Rare earth doped tantalate titanate powder and preparation method thereof
The invention relates to a rare earth doped tantalate titanate powder and a preparation method thereof. The general formula of the rare earth doped tantalate titanate powder is Cu3-xLax(TiO3)2(TaO3)2, wherein x is larger than or equal to 0.05 and smaller than or equal to 0.22. The invention further relates to a preparation method of the rare earth doped tantalate titanate powder. Potassium bicarbonate, tantalum pentoxide, lanthanum nitrate or hydrate thereof, copper nitrate or hydrate thereof, butyl titanate and citric acid are used as raw materials, absolute ethyl alcohol is used as a solvent, and the rare earth doped tantalate titanate powder is obtained through mixing, water bath stirring, drying and calcining. The rare earth doped tantalate titanate powder synthesized in the invention is relatively high in purity, no hydrolysis occurs in the synthesis process, a sintered block is compact, the dielectric coefficient is high, and the dielectric response is stable.
本发明涉及一种稀土掺杂钽钛酸盐粉体，其通式为Cu3‑xLax(TiO3)2(TaO3)2，其中0.05≤x≤0.22。本发明还涉及所述稀土掺杂钽钛酸盐粉体的其制备方法，以碳酸氢钾、五氧化二钽、硝酸镧或其水合物、硝酸铜或其水合物、钛酸丁酯和柠檬酸为原料，无水乙醇作为溶剂，通过混合、水浴搅拌、干燥煅烧得到所述稀土掺杂钽钛酸盐粉体。本发明合成的稀土掺杂钽钛酸盐粉体纯度较高，合成过程无水解发生，烧结块材致密，介电系数高，介电响应稳定。
