A method is described for the determination of oxygen in fluoride salts of yttrium, beryllium, zirconium, and magnesium and in mixtures of these salts with the fluoride salts of sodium and lithium. The fluorinating agent, potassium bromotetrafluoride, which is prepared in a nickel reactor by the addition of bromine trifluoride to potassium fluoride, is reacted with the oxides for 2 hours at 450 deg C to produce oxygen which is then measured tensimetrically. Recovery of oxygen from the pure metal oxides as standards is better than 98% with a coefficient of variation of less than 5%. The precision of analysis of the fluoride salts is better than 10%. The range of oxygen that can be measured is from 0.02 to 10 mg. (auth)
