Determination of the thermodynamic properties of titanium sponge, rare earth oxides and carbonates

The procedure is described of determining heat physical properties of titanium sponge in media controlled at temperatures up to approximately 1100 deg C obtained in an industrial apparatus. The study has been conducted with a sample located into a glass made from stainless steel; the temperature has been measured in the center and near the surface of the sample. The relationships are given between the relative heat conductivity of the titanium sponge, argon pressure and temperature, as well as between a change in heat physical constants of the titanium sponge and temperature. An artificial reaction mass has been created, and the effect of magnesium and magnesium chloride on heat physical properties has been studied. It has been established that heat conductivity for the reaction mass with magnesium chloride is much lower than that of the sponge with magnesium. Heat physical constants of oxides and carbonates of rare-earth elements are given determined with the use of the method developed
