| abstract | 1,157,317. Treating metal oxide pigments. P.P.G. INDUSTRIES Inc. 5 Aug., 1966 [9 Aug., 1965], No. 35094/66. Headings C1A and C1N. Metal oxide pigment, especially TiO 2 , produced by the vapour phase oxidation of the metal halide is digested in the presence of at least 0À1% (preferably 0À2%) of at least one Group II metal cation having an atomic weight less than 200, at a pH below 3 or from 10 to 12. The digestion is carried out at a temperature between 50 C. and the boiling point of the slurry, preferably between 80 and 90 C., for at least 5 minutes, preferably 1 to 10 hours. The pigment may be coated at the same time or subsequently with at least one hydrous oxide of aluminium, titanium and/or silicon. Exhaustive lists of suitable Group II compounds and of other suitable pigments are given. |
