PRODUCTION METHOD OF INDIUM HYDROXIDE POWDER, AND PRODUCTION METHOD OF INDIUM OXIDE POWDER

摘要

PROBLEM TO BE SOLVED: To provide a production method of an indium hydroxide powder that produces at a high yield an indium hydroxide powder having a fine and uniform primary particle diameter, and a production method of an indium oxide powder using the indium hydroxide powder.SOLUTION: An indium hydroxide powder having a fine and uniform primary particle diameter is produced at a high yield by adding a dispersant and a binder to the slurry containing the indium hydroxide powder in spray-drying. An indium oxide powder having a large specific surface area that is fine and hardly coagulates is obtained by calcining the indium hydroxide powder.
