Abstract (en)

[origin: WO2005021632A1] The invention relates to a method for producing inorganic solid substances in the form of fine particles by precipitating the inorganic solid particles thereof in a solution. The surface of the inorganic solid particles is covered (coated) by at least one additive containing at least one type of dispersing or deflocculating agent, wherein the total fraction of said additives is equal maximum to 80 mass %, preferably maximum 40 mass %, i.e. 30 mass % and even better, maximum 15 mass % of coated solids, the additive(s) being added to the initial solution. The use of the thus obtained inorganic solid substances is also disclosed.
