    摘要： A thermal insulating material based on a pigment-containing silica aerogel is obtainable bya) reacting an aqueous dispersion of sodium silicate and a pigment with a strong acid or sodium silicate with a pigment-containing strong acid to give a pigment-containing silica hydrogen, the pigment being such that it scatters, absorbs or reflects infrared radiation of wavelength 3-10 .mu.m,b) substantially freeing the resulting pigment-containing silica hydrogel from ionic constituents by washing with water,c) displacing the water in the hydrogen by a low-boiling liquid which is inert toward the pigment-containing silica gel,d) heating the liquid-containing silica gel thus obtained under supercritical conditions while completely covered with the liquid, ande) subsequently removing the liquid from the solid by flash vaporization at supercritical temperature.

    摘要： The invention relates to basic chromium aluminum sulfates which are soluble in cold water and are of the general formulaCr.sub.x Al.sub.2-x (OH).sub.2 y. (SO.sub.4).sub.3-y.n H.sub.2 Owhere 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.degree. to 200.degree. C. The molten product is converted to droplet form and allowed to solidify in free fall.
