Abstract: The invention relates to a process for the preparation of an antimony oxide-doped tin oxide pigment with a white or off-white color and a surface electrical resistance not exceeding 20 ohms/square, comprising the intimate mixing of tin oxide and antimony oxide, then heating the resultant mixture to a high temperature, in which a proportion of 1.25 to 10 parts by weight of antimony oxide Sb.sub.2 O.sub.3 per 100 parts by weight of tin oxide SnO.sub.2 is mixed and the mixture of Sb.sub.2 O.sub.3 and of SnO.sub.2 is calcined at a temperature in the range from 900.degree. to 950.degree. C.Application for the manufacture of electrically conductive white or colored paints which are useful particularly in aeronautics.
