Rare earth doped zinc-gallium-aluminum oxide powder and preparation method thereof
The invention discloses a preparation method of rare earth doped zinc-gallium-aluminum oxide powder, which comprises the following steps: sequentially adding rare earth oxide, zinc oxide, a dispersingagent and pure water into a mixing barrel, carrying out pre-dispersion to obtain a first mixed solution, and grinding the first mixed solution to obtain a first mixed slurry; sequentially adding gallium oxide, a dispersing agent and pure water into the first mixed slurry for pre-dispersing to obtain a second mixed solution, and grinding the second mixed solution to obtain second mixed slurry; sequentially adding aluminum oxide and a dispersing agent into the second mixed slurry for pre-dispersing to obtain a third mixed solution, and grinding the third mixed solution to obtain third mixed slurry; adding a binder into the third mixed slurry to obtain a fourth mixed solution, and grinding the fourth mixed solution to obtain fourth mixed slurry; and granulating, mixing and screening the fourth mixed slurry to obtain the rare earth doped zinc-gallium-aluminum oxide powder. According to the invention, the problem of non-uniform components caused by doping of large-particle-size rare earthelements into zinc-gallium-aluminum powder can be solved.
本发明揭示一种稀土掺杂锌镓铝氧化物粉体制备方法，包括：向混料桶中依次加入氧化稀土、氧化锌、分散剂以及纯水进行预分散后得到第一混合液，将第一混合液进行研磨后得到第一混合浆料；向第一混合浆料依次加入氧化镓、分散剂以及纯水进行预分散后得到第二混合液，将第二混合液进行研磨后得到第二混合浆料；向第二混合浆料依次加入氧化铝和分散剂进行预分散后得到第三混合液，将第三混合液进行研磨后得到第三混合浆料；向第三混合浆料加入粘结剂后得到第四混合液，将第四混合液进行研磨后得到第四混合浆料；将第四混合浆料进行造粒、混料和筛分得到稀土掺杂锌镓铝氧化物粉体。本申请可解决将大粒径稀土元素掺入锌镓铝粉体引起成分不均一的问题。
