【 摘 要 】
Two products of synthesis were obtained: synthesis product at a fluorination temperature of 300°C, synthesis product at a fluorination temperature of 600°C. Two source products were separated and rectified during this work. Monofraction of rhenium hexafluorides and heptafluorides were obtained. The temperatures of liquids in the system ReF6- ReF7were determined. Liquid-vapor equilibrium in the system was investigated. Viscosity and surface-tension at the liquid-to-vapor boundary are measured for liquid ReF6and ReF7.A promising method of tungsten-rhenium alloys making is a gas-phase precipitation, namely joint hydrogen reduction of these metals fluorides.
