Abstract
The present invention discloses a low-temperature co-precipitation method for fabricating TCO powders, which comprises steps: respectively dissolving two or more metals/metal salts in solvents to obtain metal ion solutions; mixing the metal ion solutions to form a precursor solution having a specified composition; enabling a co-precipitation reaction at a temperature lower than 45° C. via adding precipitant in two stages, controlling the temperature of precipitation reactions and undertaking aging processes; flushing, filtering, drying and calcining the precipitates to obtain TCO powders having a specified composition and improved quality.
