Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

For four endpoints (appearance, melting point, density and water solubility) data on the physical and chemical properties of lead telluride was taken from the handbooks CRC (2008) and Merck (2006). Waivers are proposed for boiling point, vapour pressure, partition coefficient, surface tension, flash point, explosiveness, oxidising properties, stability in organic solvents, dissociation constant and viscosity, as well as for pyrophoric properties and flammability in contact with water

No data is published for particle size distribution, auto flammability, and flammability (in air).
