The invention, which belongs to the technical field of functional material preparation, in particular relates to a preparation method of conductive powder with antimony-doped zinc oxide and stannic oxide coating monox. Pure silica powder is put into a beaker containing distilled water with the pH valued adjusted by hydrochloric acid and stirring is carried out to obtain a monox suspension; mixed liquid with Zn<2+>, Sn<4+> and Sb<3+> and an alkaline solution are controlled by a peristaltic pump to be dripped into the monox suspension simultaneously, and after dripping completion of the mixed liquid, heating and stirring are carried out continuously; ageing, suction filtration, and washing are carried out successively, an obtained precursor is dried, and then the dried precursor is placed ina muffle furnace to carry out heat treatment, so that conductive powder is obtained. The conductive powder not only has the conductive property but also has chemical stability not possessed by materials like metal and has the good antistatic performance; and the coverage rate and whiteness are high. The conductive power serving as a functional filler applied to a preparation process like of a plastic, coating, ceramic material has a wide application range.
