Description of key information

Weight of evidence approach based on two peer-reviewed data from handbooks (590 and 592 °C)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
590 °C

Additional information

Although only two values are available it can safely be concluded that the melting point of barium nitrate is relatively high, making this parameter irrelevant for both the environmental and human health risk assessment. As only two values are available, it was decided to conclude on an approximate value (590°C) instead of on a mean value.

A study on barium chloride was added in order to support the read across justification between both substances. In this study report, the melting point for barium chloride was considered to be > 600°C.
