TAILORING AND IMPROVEMENT OF LMH-2.
Abstract
Further investigation of the continuous pyrolysis process for BeH2 showed that series operation of two continuously fed, continuously discharged, stirred pot reactors was not as successful as operation of a single continuous unit. Product purities of 95-96 wt % BeH2 were obtainable from either system. Concurrently, BeO content was reduced to 3.5 wt % in product from the single reactor and 2.5 wt % from the dual reactor system. The increase in purity is attributed to high beryllium alkyl/Bayol 35 pyrolysis feed ratios. Product bulk density was also improved by use of increased agitation during pyrolysis. Sedimentation volume and glycerine mix viscosity tests predict that continuous BeH2 in its present state of development will process poorly in propellant mixes. Grinding does improve bulk density. Continuous BeH2 is comparable to ground batch-produced material in hydrolytic stability. Sedimentation volume measurements correlate well with mix viscosity of as-produced batch BeH2; however, correlation is poor for ground BeH2. Deagglomeration by air elutriation also seemed to affect its response to the sedimentation volume test.
