Use of a surface-coated tio2 base body as a white corrosion protection pigment

摘要

Invention Patent: B "WHITE PIGMENTS OF PROTECTION AGAINST CORROSION AND PROCESS FOR THE PRODUCTION OF THE SAME" D. White pigments, which consist of TiO ~ 2 ~ base bodies, for protection against corrosion, are already known. To optimize the corrosion inhibiting effect, Mn ~ 3 ~ (PO ~ 4 ~) ~ 2 ~ and one or more substances chosen from oxides, hydroxides, phosphates, hydrogen phosphates, dihydrogen phosphates and aluminum polyphosphates are precipitated on the body of TiO base ~ 2 ~.
