Unformatted text preview: DENSITY OF MOLTEN ELEMENTS AND REPRESENTATIVE SALTS This table lists the liquid density at the melting point, m , for elements that are solid at room temperature, as well as for some representative salts of these elements . Densities at higher temper- atures (up to the t max given in the last column) may be estimated from the equation ( ) ( ) t k t t = m m where t m is the melting point and k is given in the fifth column of the table . If a value of t max is not given, the equation should not be used to extrapolate more than about 20C beyond the melting point . Data for the elements were selected from the primary litera- ture; the assistance of Gernot Lang in compiling these data is gratefully acknowledged . The molten salt data were derived from Reference 1 . References 1 . Janz, G . J ., Thermodynamic and Transport Properties of Molten Salts: Correlation Equations for Critically Evaluated Density, Surface Tension, Electrical Conductance, and Viscosity Data, J. Phys. Chem. Ref.
