FIELD: metallurgy.
SUBSTANCE: method involves sampling of an electrolyte from a bath, grinding of the sample and addition of sodium fluoride to the ground sample. Then, the sample is sintered and cryolite ratio and concentration of fluorides in the sample is determined. After sintering is completed, the sample is subject to additional heat treatment till balanced phase composition of Na3AlF6, K2NaAlF6, CaF2, NaF is achieved, and cryolite ratio and concentration of fluorides in the sample is determined by means of an X-ray phase analysis.
EFFECT: improving accuracy of determination of a cryolite ratio.
