PROCEDURE FOR OBTAINING oxidic pigments, inorganic NEUTROS

摘要

Process for preparing inorganic oxidic pigments neutral starting from finely divided oxides obtained at elevated temperatures by decomposition of volatile chlorides with oxygen-containing gases characterized in that the oxide is mixed an amount at least sufficient for neutralization of an oxidic compound acids alkaline reaction of the alkaline earth metals including magnesium dry after wetting with water and drying again.
