1. Water Treatment

• Water Fluoridation: Magnesium silicofluoride (MgSiF6) is one of the compounds used to add fluoride to drinking water, a process known as water fluoridation. Fluoridation helps prevent tooth decay by strengthening tooth enamel, particularly in children.

2. Construction

• Concrete Waterproofing: Magnesium silicofluoride is also used as a concrete hardening agent and a waterproofing agent. It is been added to concrete mixes to improve their strength and reduce porosity, making them more resistant to water penetration.

3. Fabric Solutions

• Mothproofing: Magnesium silicofluoride repels or reduces the feeding activity of carpet beetles and moths. It's a highly processed chemical compound with high-grade materials, making it effective as a repellent. It's used as a repellent or feeding depressant for carpet beetles and cloth moths. 
• Waterproofing: It's used to treat fabrics, making them water-resistant. It can penetrate and seal porous materials, chemically reacting to form water-resistant layers and create hydrophobic surfaces, making it a versatile and effective waterproofing agent. 
• Dye Fixation: This process involves using chemicals or methods to create a strong bond between the dye molecules and the fibers of the fabric, ensuring that the color does not fade or run during washing or wear

4. Performance Chemicals

• Key material: Magnesium silicofluoride serve as a starting material for various chemical syntheses, particularly in reactions involving fluoride ions or for the production of other silicon-containing compounds. 
• Precursor for cryolite: It is a key precursor in the production of synthetic cryolite (Na3AlF6), a crucial component in the Hall-Héroult process for aluminum extraction. 
• Catalyst and intermediate: The compound finds use as a catalyst and intermediate in several chemical reactions.

5. Agrochemicals

• Soil Stabilizer: Magnesium Silicofluoride can be used to improve soil structure, making it more stable and less prone to erosion, which can help protect plant roots and improve water retention. 
• Active Substance Enhancer: In some formulations, it can help to stabilize and reduce the breakdown of active ingredients in agrochemicals, ensuring their effectiveness for a longer period.

6. Polymers & Resins

• Coagulant: Magnesium silicofluoride is used in the rubber manufacturing industry as a coagulant in a process called creaming. It works by accelerating the separation of rubber particles and serum in latex, which is a milky liquid containing rubber, protein, and water.
