1. Used as opaque filler, milky white agent for enamel, and acid resistant paint for iron sheet and steel plate.

2. Used as a clarifying agent and coloring agent for high-end glass such as cathode ray tubes and optical glass, it can resist exposure to sunlight and has good lamp performance. In the special glass industry such as electronic tubes, sodium antimonate can replace antimony trioxide as a glass clarifying agent because the antimony in sodium antimonate itself exists in the form of pentavalent antimony, which is beneficial for production and can also improve the transparency of glass. When using antimony trioxide as a glass clarifying agent, sodium nitrate must also be added, while using sodium antimonate does not require the addition of sodium nitrate.

3. Used as an industrial flame retardant for textiles, plastics, rubber, and other materials; Enhanced flame retardant PPA composite materials were prepared using sodium antimonate as a synergist, and compared with traditional synergist antimony trioxide in terms of mechanical properties, flame retardancy, and thermal stability. The results showed that the temperature of the composite material prepared using sodium antimonate as a synergist increased by about 30 ℃ in 5% thermal weight loss, the thermal stability of the composite material was enhanced, and there was no significant change in color during processing. The physical and mechanical properties remained unchanged, providing reference for the practical application of flame retardant modified PPA materials in specific needs [1].

4. Used for engineering plastics with low coloring power and pigment conservation; Used for enamel, acid resistant ceramics, and high-end ceramics.
