Abstract

Phase equilibria in the Li2O–B2O3–LiF ternary system are studied. It is established that the LBO primary crystallization region has a narrow concentration interval limited by Li3B7O12–LiF and Li2B8O18–LiF lines. The hydropyrolysis of LiF in air is studied. It is shown experimentally that the decomposition of LiF from the LiBO2–LiF melt at 800 °C is insignificant, but the LiF content decreases notably with time at 900 °C.
