Release to the environment of this substance can occur from industrial use: formulation of mixtures. [4] Silicon tetrachloride | SiCl4 or Cl4Si | CID 24816 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. *There is no "flour" in fluorine. 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. ›› Silicon Tetrafluoride molecular weight. We do not use a prefix for one, or mono, unless it is the second element. The bonds in tetrafluoromethane have a bonding energy of 515 kJ⋅mol −1. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. in case of consumer and professional uses). Substances which have been registered and can be placed on the EEA market by those companies with a valid registration. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. [9] Some amounts are also emitted from spontaneous coal fires. Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. Production can reach several tonnes per day. 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. Please note: Precautionary measures and guidance on safe use concern the use and handling of the specific substance as such, not of the presence of the substance in other articles or mixtures. When heated to decomposition SILICON TETRAFLUORIDE emits toxic fluoride fumes [Lewis, 3rd ed., 1993, p. 1138]. This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. English-Polish dictionary for engineers. It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. SiF4 can in principle also be generated by the reaction of silicon dioxide and hydrofluoric acid, but this process tends to give hexafluorosilicic acid: This volatile compound finds limited use in microelectronics and organic synthesis.[5]. Attacks many metals in the presence of moisture. Convert grams Silicon Tetrafluoride to moles or moles Silicon Tetrafluoride to grams. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. The described Product category (i.e. Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. For readability purpose, only non-confidential use descriptors occurring in more than 5% of total occurrences are displayed. Reacts violently to explosively with lithium nitride [Porritt, L. J., Chem. 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. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. InfoCards are generated automatically based on the data available at the time of generation. Substances listed in the EINECS, ELINCS, or NLP inventories. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). It was first synthesized by John Davy in 1812. The IUPAC name is tetrafluorosilane. 232-015-5 REACH Registration No. Its EINECS registry number is 232-015-5.
