Aqueous Solution Thermal Conductivity of Beryllium-Subgroup Metal Chlorides
The paper presents experimental data on thermal conductivity of BeCl2 and SrCl2 salt aqueous solutions in the temperature range from 20 to 300 °С and at various electrolyte concentrations in mass percent. For the first time thermal conductivity of the system Н2О + BeCl2 has been investigated at high temperatures. The experimental results are described with the help of an empirical equation in the form of: λs = λo (1+ Am + Bm 3/2 + Cm 2),where λs and λo - thermal conductivity coefficients of solution and water; A, B and C - coefficients depending on electrolyte nature; m - molality in units mol/kg. The formula error is less than ±1 %. Fig. 2. Tab. 4. Ref.: 3 titles.
