DENSIFICATION OF LMH-2.
Abstract
An effective, practical technique was found for pre-compacting and encapsulating Li-doped BeH2 prior to crystallization by hydrostatic compaction at elevated temperature. The technique employs seamless aluminum capsules fitted with solid metal plug closures and sealed with Viton O-rings. The powdered feed is pre-compacted within the capsules by use of a piston-mold unit in a platen press. The technique was successfully tested in a series of 30 crystallization experiments. No significant change in optimum crystallization conditions or polymorph distribution was observed with this new technique. The feasibility of a 'slurry' process for crystallization of BeH2 by hydrostatic compaction was also demonstrated. Hydrocarbon-wet Li-doped BeH2 was completely crystallized at temperatures ranging from 205-230 deg C and pressures of 70-140 kpsi.
