Preparación del fluoborato de litio. Determinación del ácido borico como impureza

Abstract

Three methods have been developed for the preparation of lithium fluoborate with a low content of borid acid. Several techniques have been studied to reduce the boric acid content, e. g.: whashing, extraction recrystallization and volatilizations as methyl borate. the final content of boric acid was 1,4%. The classical method of analysis (3) yields high results for the boric acid content in litium fluoborate.
