3, anti-tooth decay materials (drinking water, toothpaste, etc.).

4. Use of fungicides, insecticides, preservatives, etc.

5, small dose is mainly used for osteoporosis and Paget bone disease.

6, can be used as light metal fluoride treatment agent, smelting and refining protective agent, used as UF3 adsorbent in the nuclear industry.

7, steel and other metal cleaning fluid, flux and flux.

8, ceramic, glass and enamel flux and shading agent, leather industry raw skin and skin treatment agent.

9, as an additive in concrete, enhance the corrosion resistance of concrete.
