Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Slags, tellurium is a product of treating molten lead with sodium salts. Consists primarily of sodium-tellurium salts in various states of oxidation. No molecular formula is available for slags, tellurium.

No further substance specific data is available for slags, tellurium.

Slags, tellurium will be registered as an on-site isolated intermediate with a tonnage band of >100 t/a. Based on Article 17, Chapter 3, Title II of regulation (EC) 1907/2006, any manufacturer or importer of an on-site isolated intermediate in quantities of one tonne or more per year shall submit a registration to the Agency for the transported isolated intermediate. This registration shall include any available existing information on physicochemical, human health or environmental properties of the intermediate. Where a full study report is available, a study summary shall be submitted. According to “ECHA Guidance for intermediates, February 2008”, a registrant of an on-site isolated intermediate can provide reduced registration information according to Article 17(2) if he confirms that the substance is only manufactured and/or used under strictly controlled conditions as described under Article 17(3). For on-site isolated intermediates the information requirements on physicochemical, human health and environmental properties are limited to the data that is already available to the manufacturer (e.g. information he holds himself or that he can obtain from other sources) without any additional testing.

For slags, tellurium a substance specific literature search has been conducted (see IUCLID section 12). Since from the literature search, besides the short description stated above, no relevant data is available on physical and chemical properties of Slags, tellurium, no study summaries are provided in this section except for appearance/physical state/colour.
