Product Description
Product Description of Sodium Fluorosilicate CAS#16893-85-9
Sodium fluorosilicate is available as white crystals, crystalline powder or colorless hexagonal crystals. It is odorless, tasteless and hygroscopic, with a relative density of 2.68. It is soluble in ethyl ether, insoluble in alcohol, and more soluble in acids than in water. It decomposes in alkaline solution into sodium fluoride and silica, and breaks down into sodium fluoride and silicon tetrafluoride when heated to around 300 °C.
Product Application of Sodium Fluorosilicate CAS#16893-85-9
Sodium hexafluorosilicate is used for water fluoridation and as a raw material for opal glass and ore refining. It serves as feedstock for manufacturing fluoride chemicals including sodium fluoride, sodium hexafluoroaluminate, potassium hexafluorosilicate, ammonium fluoride and calcium fluoride. It is also applied as a flotation agent, wet etching component, wood preservative, brazing flux and welding compound, as well as an active ingredient in concrete.

FAQ
Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.
Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.
Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.
Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
