Description of key information

In a weight of evidence approach the melting point of the compound can be described as follows: 
According to the available handbook data (CRC, 2008), the melting point of lead telluride is 924 °C at atmospheric pressure.
According to the available handbook data (Merck, 2006), the melting point of lead telluride is 905 °C at atmospheric pressure.

Key value for chemical safety assessment

Additional information

According to the two handbooks the melting point of lead telluride is between 905 °C and 924 °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 value could be regarded as valid.
