The invention relates to a preparation method for preparing nano-scale oxidized zinc powder with high conductivity. The method simultaneously drip mixed salt solution of zincic soluble salt and doping elements such as aluminum, gallium, indium, Yt, scandium, tin, germanium, silicon, as well as precipitating agent into water, to generate coprecipitation to generate doped zinc bloom precursor basic zinc carbonate in condition of controlling temperature and PH value of entire reaction system, and at last, calcining the product in mixed gas atmospheres of hydrogen gas and argon gas, doped superfine zinc bloom conductive powder material can be obtained. The powder material prepared by the invention has small particle-size, uniform grain fineness distribution, and which mean particle diameter is about 10 to 80 nanometer. The electric volume resistivity of the powder can reach 2.5*10^-3 omega.cm, thus its electro conductivity is better than the sample prepared by plasma method and gas-phase method in current market. The preparation method further enhances whiteness degree and conductivity of the oxidized zinc powder, and further reduces the cost.
