Sodium Fluorosilicate - for industry, water treatment

Sodium Fluorosilicate, with the CAS number 16893-85-9, is a crucial industrial chemical known for its diverse applications across various sectors. It is available in two primary grades: Industrial and Water Treatment, each serving specific purposes.

The Industrial Grade of Sodium Fluorosilicate is widely recognized for its application in the manufacturing of opal glass, enamels, and as an insecticide and rodenticide. It is also used as a wood preservative and a chemical intermediate for producing other fluoride chemicals such as sodium fluoride and cryolite. This grade is known for its effectiveness in the timber industry as an antiseptic and in the construction materials industry as an enamel aid solvent and glass emulsion .

The Water Treatment Grade is specifically designed for use in water fluoridation programs. It is used to adjust the fluoride levels in drinking water to help prevent dental caries, providing a significant public health benefit. This grade is carefully controlled to ensure it meets the stringent standards required for consumption and is certified to NSF/ANSI 60 at a maximum use level of 2mg/L .

Sodium Fluorosilicate is a white crystalline solid that is soluble in water and ether but insoluble in alcohol. It has a relative density of 2.68 and decomposes at high temperatures, releasing toxic fumes. It is essential to handle this chemical with care due to its toxic nature, and it is classified as a hazardous substance with appropriate safety measures outlined in its Material Safety Data Sheet (MSDS) .

In summary, Sodium Fluorosilicate is an essential chemical with a broad range of applications, from industrial uses to critical roles in public health through water treatment. Its proper handling and use are vital to ensure safety and effectiveness.
