中文摘要:
      研究了电解工艺制备铟微粉时,铟离子浓度、电流密度和连续电解时间对粉体纯度和粒度的影响。结果表明:当电工艺参数为NaCl浓度80g/L,极距5cm,硫脲浓度0.3g/L,明胶浓度0.5g/L,pH=2.5,添加剂聚乙烯吡咯烷酮用量为0.2g/L时,连续电解时间越长,所得粉体粒度越大;电流密度为130A/m2时,所得粉体粒度最小,纯度最高;In3+浓度对粉体粒度的影响最小,但对纯度影响最大;在此工艺参数和In3+浓度为30g/L,电流密度为130 A/cm2的条件下电解1h,可得到粒度小于100μm的铟微粉,其中粒度小于30μm的占75%。

英文摘要:
      The effect of indium ion concentration, current density and continuous electrolysis time on the purity and size of the powder by electrolysis process was studied. The results show that:Continuous electrolysis time is longer, the larger sizes of the powder were obtained when the electric parameters are: NaCl concentration is 80g/L, polar distance is 5 cm, thiourea concentration is 0.3 g/L, gelatin concentration is 0.5 g/l, pH = 2.5, Polyvinyl ketone(PVP) is 0.2 g/L. When the current density is 130 A/m2, the particle size of the powder is the smallest, and the purity is the highest. The effect of In3+ concentration on the particle size is the least, but the influence on the purity is the most. Under the conditions of process parameters above and In3+ concentration of 30 g/L, the current density of 130 A/cm2, electrolytic for 1h, the particle size of less than 100 μm indium powder were obtained, which the particle size of less than 30 μm accounted for 75%.
