Function:
Adsorption and ion exchange properties: Sodium antimonate has certain adsorption and ion exchange capabilities. Its crystal structure enables its surface to adsorb some metal ions or charged particles, and can undergo ion exchange reactions to a certain extent. This property has potential application value in wastewater treatment, catalyst carriers, etc.
Application:
Flame retardant synergist: Sodium antimonate is an important synergist in flame retardant material systems. It is often used together with halogen-containing flame retardants (such as brominated flame retardants) to improve the flame retardant effect through synergistic effects during the combustion process.
White pigment and filler: Due to its white appearance, sodium antimonate can be used as a white pigment in materials such as coatings and plastics. It can provide a certain hiding power and whiteness, and has good compatibility with other pigments and additives. As a filler, it can also reduce material costs to a certain extent, while improving the physical properties of the material, such as increasing hardness, wear resistance, etc. It is used in the coloring and filling of some architectural coatings, industrial coatings, and plastic products.
