Additional information

A weight of evidence approach was used to address this endpoint. The values obtained were quoted in peer-reviewed handbooks and as such were awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch (1997).

The values were as follows:

Lide, D.R., et al. (2009): 1430 °C

O'Neil, M.J., et al. (2006): 1460 °C

Lewis Sr., R.J. (1995): 1460 °C.


Therefore the value selected was 1460 °C.
