Preparation method of rare earth layered hydroxide film and preparation method of YAG ceramic film
The invention provides a preparation method of a rare earth layered hydroxide film and a preparation method of a YAG ceramic film, and belongs to the field of inorganic nonmetal films. The invention provides a preparation method of a rare earth layered hydroxide film, which comprises the following steps: carrying out precipitation reaction on an aqueous solution containing soluble metal salt and hexamethylenetetramine to obtain the rare earth layered hydroxide film, the soluble metal salt comprises soluble rare earth metal salt; the total concentration of metal ions in the aqueous solution is 0.05-1 mol/L; the amount of substance of the rare earth metal ions in the aqueous solution is 95-100% of the total amount of substance of the metal ions, and the temperature of the precipitation reaction is 60-120 DEG C. OH <-> decomposed from hexamethylenetetramine under the heating condition, rare earth metal ions, anions and water generate rare earth layered hydroxide and deposit, and the rare earth layered hydroxide film is obtained by controlling the reaction temperature and the concentration of the rare earth metal ions.
本发明提供了一种稀土层状氢氧化物薄膜的制备方法、YAG陶瓷薄膜的制备方法，属于无机非金属薄膜领域。本发明提供了一种稀土层状氢氧化物薄膜的制备方法，包括以下步骤：将含有可溶性金属盐和六亚甲基四胺的水溶液进行沉淀反应，得到所述稀土层状氢氧化物薄膜；所述可溶性金属盐包括可溶性稀土金属盐；所述水溶液中金属离子的总浓度为0.05～1mol/L；所述水溶液中稀土金属离子的物质的量为金属离子总物质的量的95～100％所述沉淀反应的温度为60～120℃。六亚甲基四胺在加热条件下分解出的OH‑与稀土金属离子、阴离子、水生成稀土层状氢氧化物并沉积，通过控制反应温度及稀土金属离子的浓度得到了稀土层状氢氧化物薄膜。
