摘要： A pigment particle composition which comprises calcium carbonate particles and pigment particles, its method of manufacture and its use. According to the present invention, the calcium carbonate particles are carbonated so that they bind to each other, in which case calcium carbonate structures are generated, which comprise pigment particles and which form essentially opaque and stable pigment-calcium carbonate aggregates. It is possible to manufacture the composition by atomizing calcium hydroxide-bearing pigment slurry into a carbon dioxide-bearing gas, in which case the calcium hydroxide is carbonated in order to precipitate the calcium hydroxide particles to be attached to each other and the carbonation is continued until essentially all of the calcium hydroxide has been converted into calcium carbonate. The composition is suitable for use, among others, in paints, coating materials, fillers, polymers and printing inks.

摘要： The invention relates to a weather resistant titanium dioxide pigment with good optical properties having a SiO2 dense skin doped with metal atoms. Particularly suitable elements for doping are tin, zirconium and titanium. The SiO2 dense skin is composed of multiple layers whereby the innermost layer does not contain any significant quantity of metal atoms. The coating according to the invention is produced by adding the components to the alkaline suspension (pH at least 9) one after the other with a sliding pH. Complete formation of the doped SiO2 dense skin requires that the pH subsequently be lowered to below 9. The pigment is particularly suitable for use in surface coatings and plastics.
