It is also sold as Sodium fluorosilicate, Sodium hexafluorosilicate, Disodium hexafluorosilicate. All refer to CAS 16893-85-9. Confirm the CAS number with any supplier before ordering.
Price depends on grade, volume, packing, Incoterm and destination port, and moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a landed-cost breakdown, usually within one business day.
Sodium Silicofluoride (CAS 16893-85-9) is a white crystalline or powdery inorganic salt used for municipal water fluoridation, and as a raw material in ceramics, glass etching, wood preservation and specialty fluorine chemistry.
Standard grade offers 98.0% minimum assay. Premium grade offers 98.5% minimum with lower moisture, insolubles and free acid. Premium is recommended for water-treatment and specialty chemical uses needing consistent dosing.
No. Sodium Silicofluoride (16893-85-9) is a fluorosilicate salt, while sodium fluoride (7681-49-4) is a simple fluoride salt. Both are used in water fluoridation, but they have different solubility, dosing behaviour and handling requirements. Order by CAS to get the compound you need.
Fluoride and fluorosilicate salts are toxic and can face REACH, CLP and use-specific obligations, including drinking-water regulations for fluoridation use. We confirm the current status for your application before quoting.
Store in closed, moisture-proof containers in a cool, dry, ventilated place, away from acids, which liberate hydrogen fluoride and silicon tetrafluoride gases.
It is treated as a toxic dangerous good (Class 6.1, UN 2674; always confirm on the current SDS). We pack it in UN-approved containers, apply CLP labels and ship through licensed forwarders under IMDG for sea and ADR for European road.
Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.
REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
