Useful:

• Description: As a type of fluorosilicate, potassium fluorosilicate can be used as fluoridizing agents for water supplies, in the production of synthetic cryolite, and in metal plating. Potassium fluorosilicate can be used as oral care ingredient, as a fluxing ingredient in porcelain enamels, and as wood preservative elements. Potassium fluorosilicate can also be used for the manufacture of ceramic materials and optical glasses.
• Uses: In the manufacture of opalescent glass, in porcelain enamels, in insecticides. Also used in aluminum metallurgy. Potassium hexafluorosilicate is used in the production of porceleins. It is also used for the preservation of timber. It is involved in the manufacturing of ceramics, aluminum and magnesium smelting. In addition, it is used as an intermediate in the manufacturing of optical glass.

Technology Process of Potassium fluorosilicate

There total 8 articles about Potassium fluorosilicate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
