Description of key information

Weight-of-evidence approach: According to published literature (Sorokin, 1966), K2TiF6 is thermally stable at least up to 400°C, with some phase transformation and conversion to oxi-fluorides and oxides happening at higher temperatures. One publications (Chernov, 1973) states a definitive melting point at 899°C. The figure reported in the Gmelin Handbook of inorganic chemistry (cited from Ginsberg,H., 1932) of ca. 780°C is selected as the key value for the chemical safety assessment.
