ITO powder and method for manufacturing same, coating material for electroconductive ITO film, and transparent electroconductive film

摘要

The change in resistance over time of a low-resistance acicular ITO powder is reduced, and the stability of the ITO powder in ambient air is improved. Tin-containing indium hydroxide baked in an atmosphere of an inert gas and reducing gas is processed for a predetermined time under a water-containing atmosphere of inert gas and/or reducing gas at a temperature of 0°C or greater and 100°C or less, and is then exposed to air.
