High Thermal Stability at Room Conditions: Stable under normal temperature and pressure, ensuring safe handling and storage.

Controlled Solubility: Slightly soluble in inorganic acids and cold water, soluble in hot water, and insoluble in ammonia, providing flexibility for selective applications.

Well-Defined Physical Properties: Exists as colorless monoclinic flaky crystals with a density of 3.012 g/mL, melting point of 780 °C, and boiling point of 235–237 °C, facilitating predictable processing behavior.

Useful Thermal Decomposition: Decomposes above 500 °C to yield titanium dioxide and potassium fluoride, enabling its use in titanium-based material synthesis.
