Abstract: cf. CA 58, 5038f. F was detd. in NaF, MgF₂, CAF₂, AlF₃, and Na₃AlF₆ by the pyrohydrolytic method. TiO₂ was a more effective activator in most cases than Al₂O3. The optimum hydrolysis temp. and time in min. for the individual fluorides (with TiO₂) was: NaF (anal.) 1000°, 30; MgF₂ (pure) 1000°, 33; CaF₂ (pure) 900-1200°, 105-24; AlF₃ (techn.) 1100°, 63; AlF₃ (sublimed) 900°, 36; Na₃AlF₆ (techn.) 1000°, 24; Na₃AlF₆ (pure) 1000°, 31.
