Used as a wood preservative due to its ability to protect against fungal decay and insect damage. It is also employed in the textile industry as a mordant to help fix dyes onto fabrics. Additionally, it finds use in the production of specialty glasses and ceramics where fluoride and magnesium components are required, improving coating properties for enhanced scratch and corrosion resistance. Its antimicrobial properties make it suitable for certain industrial preservation applications. Furthermore, it is used in water treatment processes to control fluoride levels to safe standards and serves as an intermediate in the production of other fluorine-containing chemicals.
