A simple and economical process for the preparation of polyphosphates of organic bases consists of reacting a mixture of phosphorus pentoxide and at least one organic nitrogen base with at least one compound which releases water accompanied by decomposition under the prevailing conditions in such a molar ratio that upon decomposition of the water-releasing compound at most essentially 2 mol. water are produced per mol. phosphorus pentoxide. Thus-prepared polyphosphates are particularly suitable as flame-protection agents for plastics.

An active heavy metal-free and non-toxic anti-corrosion pigment based on phosphate, which is particularly environmentally friendly, is a mixture of .beta.-tricalcium phosphate and tertiary magnesium phosphate or dicalcium phosphate dihydrate. It has good compatibility with the usual raw materials of paints and additives.
