Sodium antimonate is widely used as a flame retardant in various materials, including plastics, textiles, polymers, and coatings. It works by releasing antimony oxide when exposed to heat, which helps to suppress combustion and reduce the spread of flames. This makes it particularly valuable in industries where fire safety is critical, such as in the production of electrical cables, automotive components, and construction materials. Additionally, it is employed in the manufacturing of certain types of glass and ceramics, where it acts as a fining agent to remove bubbles and improve clarity and durability. In the production of lead-acid batteries, sodium antimonate helps to increase efficiency and extend battery life. Furthermore, it is used as a catalyst in certain chemical processes and as an additive in paints and coatings to improve stability and adhesion properties. Its ability to enhance fire resistance and material quality makes it a versatile and essential compound in industrial applications.
