Rare earth doped indium gallium zinc oxide powder as well as preparation method and application thereof
The invention relates to a preparation method of rare earth doped indium gallium zinc oxide powder. The method comprises the following steps of: sequentially adding water, a dispersing agent, galliumoxide powder and rare earth oxide powder into a first mixing barrel to perform pre-dispersion on the added raw materials, and grinding an obtained pre-dispersed solution to obtain first mixed slurry;sequentially adding water, a dispersing agent and zinc oxide powder into a second mixing barrel to perform pre-dispersion on the added raw materials, adding an obtained pre-dispersed solution into thefirst mixed slurry to perform grinding so as to obtain second mixed slurry; sequentially adding water, a dispersing agent and indium oxide powder into a third mixing barrel for pre-dispersing, and adding an obtained pre-dispersed solution into the second mixed slurry so as to perform grinding to obtain third mixed slurry; adding an adhesive into the third mixed slurry, and performing grinding toobtain fourth mixed slurry; and granulating, mixing and screening the fourth mixed slurry to finally obtain the rare earth doped indium gallium zinc oxide powder. According to the preparation method of the invention, the problem of non-uniform components caused by doping of large-particle-size rare earth elements into IGZO powder can be solved.
本发明涉及一种稀土掺杂铟镓锌氧化物粉体制备方法，包括：向第一混料桶中依次加入水、分散剂、氧化镓粉末以及氧化稀土粉末进行预分散，把预分散的溶液进行研磨后得到第一混合浆料；向第二混料桶中依次加入水、分散剂以及氧化锌粉末进行预分散，把预分散的溶液加入第一混合浆料中进行研磨后得到第二混合浆料；向第三混料桶中依次加入水、分散剂以及氧化铟粉末进行预分散，把预分散的溶液加入第二混合浆料中进行研磨后得到第三混合浆料；向第三混合浆料中加入黏结剂，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，最终得到稀土掺杂铟镓锌氧化物粉体。本申请可解决将大粒径稀土元素掺入IGZO粉体引起成分不均一的问题。
