The thermo-stability of K_2TaF_7 in air and argon atmosphere was investigated by means of thermo-differential, thermo-gravimetric and chemical analyses and also X-ray powder diffraction method. An obvious heat-absorbing effect was observed at 218°±3℃ with the appearance of break-up of larger crystals. The melting point of K_2TaF_7 was measured to be 730°±3℃. During the course of heating, by the action of moisture in air, K_2TaF_7 was hydrolyzed into K_2TaO_2F_3 which is soluble in molten K_2TaF_7 and thus...

The thermo-stability of K_2TaF_7 in air and argon atmosphere was investigated by means of thermo-differential, thermo-gravimetric and chemical analyses and also X-ray powder diffraction method. An obvious heat-absorbing effect was observed at 218°±3℃ with the appearance of break-up of larger crystals. The melting point of K_2TaF_7 was measured to be 730°±3℃. During the course of heating, by the action of moisture in air, K_2TaF_7 was hydrolyzed into K_2TaO_2F_3 which is soluble in molten K_2TaF_7 and thus affects its melting point. This might throw light on the disagreement of the melting points of K_2TaF_7 determined by the various authors. The end product of hydrolysis of K_2TaF_7 was identified to be KF and KTaO_3 (potassium meta-tantalate). Finally, the different stages of hydrolytic reaction of K_2TaF_7 and its relation with various temperatures were discussed.
