Abstract: The formation of potassium oxofluorotantalates and potassium oxotantalates in the system KF— K₂TaF₇—Ta₂O₅ was investigated. A general reaction scheme was suggested based on the approach of “figurative points diagram”. Experimental testing of the reaction scheme revealed the stability of only certain potassium oxofluorotantalates. The summary of all known potassium oxofluorotantalates is given and some corrections of former data on existence of certain compounds are discussed.
