The invention discloses a preparation method of spherical nano-scale and highly dispersed ITO powder. Indium tin mixed salt solution is prepared by using indium salt and tin salt solution as raw materials; ammonia solution is used as precipitating agent; and then indium tin mixed salt solution and precipitation are prepared The agent solution is atomized by the atomizer to form a tiny liquid mist, which is sprayed into the reaction chamber in a counter-spray manner to generate a mixture of indium hydroxide and tin hydroxide with uniform and spherical particles, which is cleaned, dried and calcined to obtain nano-ITO. Powder, the ITO powder prepared by the invention is spherical, nano-scale and highly dispersed, and the grain size is uniform, which greatly improves the comprehensive performance of the ITO powder. |
