THE STRONTIUM-STRONTIUM HYDRIDE PHASE SYSTEM

Technical Report ·
OSTI ID:4634011

The Sr--SrH/sub 3/ phase diagram was studied by thermal analysis, chemical analysis of equilibrated phases, and x-ray diffraction. The maximum solubility of SrH/sub 2/ in strontium metal is 38 mole% at the peritectic temperature of 880 deg C. Strontium metal undergoes an allotropic transfnrmation at 555 deg C and melts at 768 deg C. A second transformation was found, at about 240 deg C, in samples containing hydrogen. Strontium hydride was found to have an allotropic transformation at 855 deg C. (auth)
