DETERMINATION OF VAPOR PRESSURE IN SOLID ANHYDROUS YTTRIUM AND SAMARIUM CHLORIDES

The vapor pressure was determined for saturated yttrium trichloride at 498 to 625 deg C and for samarium chloride at 501 to 582 deg C. The data on the vapor pressure as a function of temperature and the heat of sublimation, calculated by the least squares method, are tabulated. (R.V.J.)
