Claims8
A production method of ITO particles, comprising:
- obtaining ITO particles by causing a reaction at a temperature from 180° C. to 240° C. for 12 hours to 120 hours in a solution containing In salt from 0.09 M to 0.9 M, Sn salt from 0.01 M to 0.2 M, a basic compound, and a solvent containing at least one kind of methanol, ethanol, and isopropanol.
A production method of dispersion, comprising:
- obtaining ITO particles by causing a reaction at a temperature from 180° C. to 240° C. for 12 hours to 120 hours in a solution containing In salt from 0.09 M to 0.9 M, Sn salt from 0.01 M to 0.2 M, a basic compound, and a first solvent containing at least one kind of methanol, ethanol, and isopropanol;
- washing the ITO particles;
- and
- dispersing the washed ITO particles, in a second solvent.
