Thermal stability of potassium fluorooxalatozirconates
Thermal decomposition of fluorooxalatozirconates (FOxZs) K 3 ZrF 5 C 2 O 4 , K 2 ZrF 4 C 2 O 4 ⋅ 2H 2 O, KZrF 3 C 2 O 4 ⋅ 3H 2 O, and Zr 4 O 3 F 2 (C 2 O 4 ) 4 ⋅ 2H 2 O in air flow is studied. Crystalline K 2 ZrF 4 C 2 O 4 and KZrF 3 C 2 O 4 are detected. The decomposition onset temperature of anhyd...
