Abstract:

Fansteel-80, Ta, Mo, graphite and BN were suitable containment materials for molten lithium metaborate for at least 24 hr in an Ar atmosphere. Fansteel-80 was tested with Li etaborate for 87.5 hr at 1600 F in an Ar atmosphere. No evidence of leakage or contamination of the Li metaborate was noted. CaSi2 was extremely corrosive to all metals including the refractory metals. It was successfully contained in BN for 36 hr. Ceramics and cermets now appear to be the only potential long duration containment materials for CaSi2. The heat content measurements on CaSi2 were extended to 1780 F . A crucible, fabricated from a new type of graphite was installed. This graphite was compatible with Li metaborate. The density of molten Li metaborate was determined between 1570 and 2040 F. The viscosity of this material was determined between 1570 and 1960 F.
