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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 273-701-4 | CAS number: 69011-60-5 Oxides formed during melting, refining, and casting of solders. Major constituents are oxides of tin, lead and antimony; minor constituents are iron, nickel, sulfur, arsenic, copper and silver.

Description of key information
Additional information
Substance: Lead alloy, base, Pb Sn dross
SIP description: 'Lead alloy, base, Sn, Pb, dross' is a solid in granular or particulate form. It is produced by skimming the precipitate surface layer formed during the production and/or use of lead-tin alloys under oxidising conditions. 'Lead alloy, base, Sn, Pb, dross' is composed primarily of lead and tin in oxide and/or metallic form, and may contain amounts of sodium, copper and antimony in oxide, silicate, sulphide and/or metallic forms. |

The substance is a grey to brown, odourless solid (at 20°C and 101.3 kPA) in a compact form or in the form of particulates.
The density will vary according to the precise composition of the sample. The density of the tested sample was 2.08 g/cm3. The melting point is shown to be > 500°C. Consequently, boiling point and vapour pressure cannot be determined. The water solubility test shows dissolution of metal ions. One sample was tested for granulometry, a D50 = 51 µm was determined. Both the results of the water solubility test and the granulometry test should be used with caution.
There is no evidence of physical hazards in terms of (auto) flammability, explosivity and oxidising properties.
Studies regarding boiling point, vapour pressure, partition coefficient,dissociation constant,surface tension, flash point, stability in organic solvents, and viscosity do not need to be conducted.
Waivers are in place for all these endpoints .
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
