✦ Synopsis

Pressure vs composition (P-C) isotherms for the UH system for temperatures of 700-1065°C and pressures to 137.89 MPa are shown. The sample was contained in a concentric vessel and located within a secondary vessel. Plateau pressure at 1065°C is 700 atm. The single-phase region on the hydrogen-rich side starts at a H/U ratio of 2.35. Physical property measurements showed a thermal conductivity, k, value of 0.003 cal/cm s K, R c = 50. Experimentally determined plateau pressures are compared with values obtained by other workers. The UH system retains broad, two-phase plateaus at temperatures to 1065°C. The critical temperature must be above 1065°C.

A new isothermal flow calorimeter for gases at high temperatures and pressures is described. The calorimeter employs a throttling-capillary tube to provide both the pressure drop and the heating element. Considerable care was taken to operate the calorimeter in an isothermal environment by use of a
