A mixture of fluorine and helium
The mixture of fluorine and helium mainly has the following situations:
1. Manufacture of hydrofluoric acid (HF);
2. Make plastics;
3. Sodium fluoride (NaF), a pesticide;
4. Fluoride in drinking water and toothpaste helps prevent tooth decay;
5. Oxidants in rocket fuel, separation of uranium isotopes, welding and cutting of metals, electroplating, glass processing, raw materials for halogenated fluorine, manufacturing of fluorides, fluorinated plastics, fluorinated rubber, etc., drugs, pesticides, rodenticides, refrigerants, plasma etching.
