INDIUM TIN OXIDE POWDER METHOD FOR PRODUCING SAME DISPERSION PAINT AND FUNCTIONAL THIN FILM

摘要

indium tin oxide powder particle size median diameter distribution of 30 ~ 45 and, the D ₉₀ is less than 60 . This production method is an indium tin oxide powder, and using a divalent tin compound, a pH of 4.0 ~ 9.3, the liquid temperature by a 5 & 0 & C or more conditions, the dry powder of indium tin hydroxide having the hue of amber colored gold to process and (A) for co-precipitation, wherein the indium tin hydroxide and dried and fired to obtain an indium tin oxide process (B), provided with the indium tin oxide obtained a step (C) to dry milling in a nitrogen atmosphere in this order . ;
