Description

Potassiumsilicofluoride is an inorganic salt with the chemical formula K₂SiF₆, widely recognized for its utility as a source of fluoride ions and silicon. This compound is valued for its role in industrial processes requiring controlled fluoride release, surface treatment, and mineral synthesis. It is a critical raw material for manufacturers in the ceramics, metallurgy, and agricultural chemical industries seeking consistent quality and reliable supply.

Application

As a fluxing agent and opacifier in the production of ceramics, glass, and enamel.
In metal surface treatment and aluminum refining processes.
As a key ingredient in the manufacture of insecticides, rodenticides, and wood preservatives.
In the synthesis of other silicon and fluoride-based compounds.
For water fluoridation and as a component in certain dental products.
In the production of synthetic mica and other specialty minerals.
As a laboratory reagent in analytical chemistry and research.

Quality Control

Our Potassiumsilicofluoride is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and bases. Due to its nature as a fluoride/strong alkali, ensure the storage area is separate from reactive substances. Maintain ambient temperature conditions (15-25°C) and control humidity to prevent caking.
