M. Almansour et F. Wallrafen, THE PHASE-RELATIONS IN THE QUASI-BINARY SYSTEM LIBAF3-ALF3 - A SEARCHFOR NEW FLUORIDE LASER HOSTS, Crystal research and technology, 28(5), 1993, pp. 707-710
In a search for new fluoride laser host materials (esp. with an Al sit
e for Cr3+ doping) the phase relations in the join LiBaF3-AlF3 of the
ternary concentration diagram LiF-BaF2-AlF3 were investigated by diffe
rence thermal analysis method from 15 samples with different compositi
ons. A new congruently melting compound LiBaAlF6 (T(m) = 785-degrees-C
) was found. The alpha-beta-phase transformation at 671-degrees-C prev
ents the growth of beta-LiBaAlF6 single crystals from the own melt and
the application to laser technology.
