Method for preparing ITO (Indium Tin Oxide) granulation powder by mixing method
The invention relates to a method for preparing ITO (indium tin oxide) granulation powder by a mixing method. The method comprises the following steps: (1) weighing indium oxide and tin oxide powder for later use; (2) dissolving a dispersing agent and a binder in deionized water; (3) dispersing indium oxide and tin oxide powder into the solution obtained in the step (2); (4) putting the slurry into an ultrasonic instrument for pre-dispersion to obtain slurry to be ground; (5) putting the slurry to be ground into a ball mill for grinding; (6) adding a defoaming agent into the slurry, and stirring for defoaming; and (7) carrying out spray drying on the mixed slurry to obtain the ITO granulation powder. According to the method, by adding all materials and additives (the dispersing agent and the binder) at the same time, pre-dispersing the slurry under the combined action of ultrasonic treatment and stirring and putting the slurry into a grinding machine for sanding, the advantages that the grain size of the target material is small and uniform can be obtained through a mechanical mixing method, and the problem that good component uniformity and high activity are difficult to obtain atthe same time when ITO particles are prepared through a mixing method is solved.
本发明涉及一种混合法制备ITO造粒粉体的方法，包括以下步骤：（1）称取氧化铟和氧化锡粉体备用；（2）分散剂和粘结剂溶于去离子水中；（3）将氧化铟和氧化锡粉体分散于步骤（2）的溶液中，（4）将浆料放入超声波仪器中进行预分散，得到待研磨浆料；（5）将待研磨浆料置于球磨机中进行研磨；（6）往浆料中加入消泡剂，搅拌进行消泡；（7）将混合浆料进行喷雾干燥，得到ITO造粒粉。该方法将所有物料和添加剂（分散剂、粘结剂）同时加入，超声与搅拌共同作用将浆料预分散后，再投入研磨机进行砂磨，既能利用机械混合法获得靶材的晶粒尺寸小且均匀的优点，又解决了混合法制备ITO粒时存在的良好成分均匀性和高活性难以兼得的问题。
