Thermal decomposition of fluorooxalatozirconates (FOxZs) K3ZrF5C2O4, K2ZrF4C2O4 ⋅ 2H2O, KZrF3C2O4 ⋅ 3H2O, and Zr4O3F2(C2O4)4 ⋅ 2H2O in air flow is studied. Crystalline K2ZrF4C2O4 and KZrF3C2O4 are detected. The decomposition onset temperature of anhydrous products goes down as the K/Zr molar ratio decreases. Disproportionation of potassium FOxZs both at the oxalate group yielding K2ZrF4C2O4 and ZrO2–x/2Fx, K2C2O4 and K3ZrF7 and at fluorine yielding K3ZrF7 and ZrO2 takes place. FOxZs can be used as precursors to produce fine-grained ZrO2 (baddeleyite).
