熔融盐的密度表

DENSITY OF MOLTEN ELEMENTS AND REPRESENTATIVE SALTS This table lists the liquid density at the melting point, ρm , for elements that are solid at room temperature, as well as for some representative salts of these elements. Densities at higher temperatures (up to the t max given in the last column) may be estimated from the equation

ρ(t) = ρm - k(t-t 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 20°C beyond the melting point.

Data for the elements were selected from the primary literature; the assistance of Gernot Lang in compiling these data is gratefully acknowledged. The molten salt data were derived from Reference 1.
