发明名称 Preparation of phosphates by induction melting
摘要 Phosphates, e.g., the polyphosphates and halophosphates, are prepared in high purity by melt thermocondensing corresponding precursors thereof, e.g., salts of orthophosphoric, pyrophosphoric or metaphosphoric acid, via electromagnetic induction heating, for example in an auto-crucible furnace.
