Other relevant information includes the following: To see the full list of notified classifications and to get more information on impurities and additives relevant to classification please consult the C&L Inventory. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. The date of the last update corresponds to the publication date of the InfoCard and not necessarily to the date in which the update occurred in the source data. The described Product category (i.e. Production can reach several tonnes per day. In the laboratory, the compound is prepared by heating BaSiF6 above 300 °C, whereupon the solid releases volatile SiF4, leaving a residue of BaF2. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. Dangerous Goods List (ADN, Chap. It is used for Reacts violently with alcohols to form HF. This section provides links to the list of precautions (precautionary statements) and to the guidance on safe use, if they have been provided in REACH registration dossiers. The EC or list number is the primary substance identifier used by ECHA. Information on precautionary measures and the safe use is submitted by the registrant of a substance and the registrant is solely responsible for its accuracy and completeness. the electronic edition of the Official Journal of the European Union. When information is available in all sources, the first two are displayed as a priority. This is unique source of information on the chemicals manufactured and imported in Europe. Attacks many metals in the presence of moisture. This site is not fully supported in Internet Explorer 7 (and earlier versions). It applies the European Agreements on the international transport of dangerous goods by road (ADR) and inland waterways (ADN), and the Regulations concerning the international carriage of dangerous goods by rail (RID).

The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. If generated, an InChI string will also be generated and made available for searching. The Waste Framework Directive aims to protect the environment and human health from the generation and management of waste and to improve efficient use of resources. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard. Reacts violently to explosively with lithium nitride [Porritt, L. J., Chem. Silicon = 1 Tetra = 4. This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. The source of the information is mentioned in the introductory sentence of the hazard statements. When heated to decomposition SILICON TETRAFLUORIDE emits toxic fluoride fumes [Lewis, 3rd ed., 1993, p. 1138]. Molecular weight calculation: 28.0855 + 18.9984032*4 âºâº Percent composition by element Note that rounding errors may occur, so always check the results. Use descriptors are adapted from ECHA guidance to improve readability and may not correspond textually to descriptor codes described in Chapter R.12: Use Descriptor system of ECHA Guidance on information requirements and chemical safety assessment. Search results for tetrafluoride at Sigma-Aldrich. Attacks many metals in the presence of moisture. SiF4 is a by-product of the production of phosphate fertilizers, resulting from the attack of HF (derived from fluorapatite protonolysis) on silicates, which are present as impurities in the phosphate rock. The chart below shows the calculated isotope pattern for the formula SiF 4 with the most intense ion set to 100%. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. When heated to decomposition SILICON TETRAFLUORIDE emits toxic fluoride fumes [Lewis, 3rd ed., 1993, p. 1138]. It is a gaseous form with the chemical formula SiF4. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Tetrafluoride definition, a fluoride containing four fluorine atoms.
