摘要：
In a method for manufacturing alkalimonofluorophosphate of general formaula M2PO3F (I), where M stands for the cation of a metal of the first main group of the periodic system, in particular potassium, a reaction mixture containing alkali metal cations M, phosphate, fluoride, particularly in the form of alkali hydroxyde, phosphoric acid and hydrofluoric acid, and water, the molar ratio of M:P:F being (2±0,1):(1±0.05):(1±0.1) and the molar ratio of water:P being at least 1:1, is heated to a temperature of 150 °C to 400 °C. Alkalimonofluorophosphate of general formula (I) occurs, with evaporation of water, as a reaction product, which is then isolated.
