    摘要: A process for the preparation of a hydrolyzable titanyl sulphate solution comprising adding sulphuric acid having a concentration greater than about 86% to a ternary mixture of two slags and an ilmenite to bring the proportion by weight of H.sub.2 SO.sub.4 to TiO.sub.2 to from about 1.7:1 to 2.2:1 and adding water, dilute sulphuric acid or oleum in amount sufficient to bring the H.sub.2 SO.sub.4 concentration to from about 86 to 96%, thereby to form the titanyl sulphate solution, the first slag having a TiO.sub.2 content greater than about 80% and a Ti(III) content of about 22 to 40%, the second slag having a TiO.sub.2 content of about 60 to 80% and a Ti(III) content of about 5 to 15%, and the ilmenite having a ratio of Fe(III) to Fe(II) of from about 1:1 to 10:1, the slags and ilmenite being present in such proportions that the ternary mixture of raw materials obtained has a molar ratio of Ti(III) to Fe(III).gtoreq.1.4.

    摘要: An inorganically after-treated TiO.sub.2 pigment with a coating of hydrophobicizing and hydrophilicizing organic substances, which pigment comprises more than about 95% by weight of TiO.sub.2, shows a loss on annealing of less than about 0.8% (after subtraction of the carbon content) and has a grindometer value smaller than about 30, corresponding to a value of more than about 5.6 on the Hegman scale, is produced by micronizing a mixture of an inorganically after-treated TiO.sub.2 pigment, an untreated TiO.sub.2 pigment and hydrophobicizing and hydrophilicizing organic substances, the after-treated pigment being employed in about 1 to 40% by weight of total TiO.sub.2 pigment and the hydrophobicing and hydrophilicizing substances being employed in about 0.3 to 5% by weight of TiO.sub.2 pigment. The pigments are readily dispersible which simplifies their use in pigmenting lacquers, plastics and paper.
