Surface tensions of inorganic compounds and mixtures

This article is part of a series, the first of which is the Surface and interfacial tensions.

The coefficients shown in the tables are based on variations in surface tension as a function of temperature. In general, the first column gives the name of the compound, in alphabetical order. The second column gives a reference temperature (in K) at which experimental measurements of surface tension have been made. This temperature is either the melting temperature, ambient temperature or another temperature close to ambient. The third column shows the experimental surface tension (in 10 ^{– 3} N · m ^{– 1} ) measured at the reference temperature. In the fourth column, the coefficient ${\sigma }_{\text{a}}$ (10 ^{– 3} N · m ^{– 1} ) of the equation representing the variation in surface tension as a function of temperature is given:

In the fifth column, the coefficient b is tabulated: $b=\frac{\partial \sigma }{\partial T}$

In the sixth column, the temperature range corresponds to the range in which the (1) equation applies; when not indicated, it is a few tens of degrees around the reference temperature (column 2). In the seventh column, the critical temperature of the compound is reported, either taken from the literature or estimated. In the eighth and ninth columns respectively, the coefficients ${}_{}$
