Remarks on result:

other: 2.29E-42 Pa

The following information has been provided via ITRI as a personal communication from the National Physical Laboratory:

The vapour pressure of pure tin at 25 °C is extremenly small. A calculation using our MTDATA thermodynamics code indicates a pure tin vapour pressure of 2.29E-42. In the presence of limited amounts of oxygen, the SnO(g) species (theoretically) becomes the most significant source of tin in the gas. MTDATA calculates the partial pressures as:

pp(Sn) = 2.29E-42 Pa

pp(SnO) = 1.18E-40 Pa

If oxygen is in excess, the SnO2 soild phase forms and the concentration of tin containing species falls dramatically. This exercise may be repeated with other possible tin transport agents (e.g. H, Cl). In most cases an enhancement over the pure tin vapour pressure would be expected.

Conclusions:

The vapour pressure of tin is 2.29E-42 Pa

Executive summary:

The vapour pressure of tin was reported to be 2.29E-42 Pa

Description of key information

A number of articles in the public domain, published papers and Safety Data Sheets record the vapour pressure of tin as ranging from 2.29E-42 at 25 °C up to 133.332 Pa at 1609 °C

Vapour pressure:

1 497 K

Additional information

The range of values for the vapour pressure of tin covers a large range of results across a range of different temperatures. The vapour pressure of tin is relatively small and is difficult to measure accurately at low temperatures. The resulting margins of error are quite high and can be complicated if there is any chance of volatilisation by tin compounds e.g. oxides or sulphides.

Two of the results have vapour pressures of 0.08 mm Hg (equivalent to 1.06 Pa) and 1 Pa at 1224 °C. On the basis that these are the only consistent results within the dataset a value of 1 Pa at 1224 °C has been selected.
