The evaporation range and vapor pressure of TiC, ZrC, HfC, NbC, Cr/sub 3/ C/sub 2/, TiB/sub 2/, ZrB/sub 2/, CrB/sub 2/, SrB/sub 6/, AlB/sub 12/, TiN, NbN, Ta/sub 2/N, and MoSi/sub 2/ were determined at 1100 to 2000 deg C by the Langmuir method, and the heats of evaporation were calculated. It was found that all the compounds evaporate as molecular complexes except AlB/sub 12/, which dissociates by expelling aluminum. (R.V.J.)
