Indium Tin Oxide nano-powder was prepared with a convenient solvent thermal method. A hydroxide precursor was first prepared from indium chloride and tin chloride by using ammonia as precipitating agent.
以氯化铟和氯化锡为原料，氨水为沉淀剂，先用化学沉淀法制备了前驱体，然后将该前驱体以乙二醇为溶剂在聚四氟乙烯内衬的反应釜中于低至190 ℃下反应，获得了铟锡氧化物纳米粉体。
The production process is developed by ourselves, which has reached the international level. We have also developed a series of deep processed products of Indium such as High-purity Indium(99.999%, 99.9999%), Indium Chloride, Indium Oxide, Indium Nitrate, Indium Sulphate, Indium Hydroxide, Indium Shot, Indium Sheet, Indium-Tin Alloy, ITO Powder, etc.
生产工艺是自主开发的，具有国际先进水平，并开发出了高纯铟（99.999%、99.9999%）、氯化铟、氧化铟、硝酸铟、硫酸铟、氢氧化铟、铟粒、铟片、铟锡合金、ITO纳米粉体等一系列铟的深加工产品，另外，公司还生产饲料级氧化锌、硫酸亚铁、硫酸锌。
The conditions of drenching the indium out from the ferric hydroxide with sodium hydroxide are studied, and ninety percent of indium can be drenched out with saturation sodium hydroxide for three times.
用氢氧化钠从含铟的氢氧化铁中浸取铟的条件进行了研究，发现用饱和的氢氧化钠浸取三次可得到90%以上的铟。
In ammonia solution, ferric hydroxide was used as a coprecipitating reagent to concentrate indium, bismuth and lead so that to separate the three elements from the massive zinc, could avoid the interference from the base substance.
采用在氨溶液中以氢氧化铁为共沉淀剂，共沉淀富集铟、铋和铅等元素，并与大量锌分离，消除基体的干扰。
Compound oxide CaO-In2O3 powder was synthesized with solution of soluble calcium and indium salt which are under given Mole proportion and hydroxide as precipitator by chemical co-precipitation.
采用共沉淀方法，以一定摩尔比的可溶性钙盐和铟盐为源物质，以氢氧化物作为沉淀剂，制备出了CaO-In2O3复合氧化物粉末。
