Description of key information

Decomposition temperature: approx. 1600 °C

Key value for chemical safety assessment

Additional information

According to reliable handbook data (e.g. Merck Index) barium sulphate decomposes at approx. 1600°C. Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, the decomposition temperature of approx.1600°C could be regarded as valid.
