摘要

The invention relates to a corrosion-protective pigment for protecting the surfaces of metals or metal alloys. Said pigment is therefore used especially for protecting metal parts or metal alloy parts from corrosion. The pigment is characterised in that it is a) a mixture and/or a reaction product of acid aluminium tripolyphosphate with calcium and magnesium oxide, hydroxide or carbonate and/or b) hydroxylapatite and/or c) a mixture and/or a conversion product of hydroxylapatite with trimagnesium phosphate.
