    Abstract: The invention relates to basic chromium aluminum sulfates which are soluble in cold water and are of the general formula CrxAl2-x(OH)2y. (SO4)3-y.n H2O where x is from 0.1 to 1.9, y is from 0.01 to 2 and n is from 4 to 24, and a process for the preparation thereof. The process comprises reacting chromium (III)-containing waste sulfuric acid having a water content of 20-50% by weight with aluminum oxide and/or aluminum oxide hydroxide and/or aluminum hydroxide at a temperature of 100 DEG to 200 DEG C. The molten product is converted to droplet form and allowed to solidify in free fall.

    Abstract: Thermostable bismuth vanadate/molybdate pigments are prepared by precipitating onto a pigment, obtained by calcination, of the formula Bi VO4.Bi2Mo O6 where n is 0.2-2.5, in aqueous suspension at 70 DEG -100 DEG C. within the pH range from 4 to 9.5 a first SiO2-containing layer using an alkali metal silicate solution of a magnesium hexafluorosilicate solution, maintaining the suspension at 70 DEG -100 DEG C. for not less than 1 hour, producing a thick coating on the precoated pigment by adding further alkali metal silicate solution, magnesium hexafluorosilicate solution or a mixture of the two within the pH range from 4 to 9.5, and finally depositing wax on the SiO2-containing layer by means of a waxing emulsion/dispersion, the products showing, compared with the starting pigment, an appreciably improved thermal stability in plastics.
