Abstract
Stoichiometric, stable fluorides for comparison standards in neutron activation analysis were prepared by horizontal zone-refining or sublimation in HF atmospheres. The fluorides of Na, Mg and Al were shown by thermogravimetry to be anhydrous and to remain water-free after exposure to room air. Fluorine in the purified samples was separated by the pyrohydrolysis method and subsequently measured by acid-base titrimetry or selective ion electrodes. Deviations from theoretical values were ±0.1, ±0.9 and ±2.8% respectively for fluorides of Na, Mg and Al.
