Application of nitrogen in other fields: Nitrogen is the main component of air. It is a colorless, odorless, non-toxic and non-flammable gas at room temperature and atmospheric pressure. The boiling point is -195.8 °C and its chemical properties are inactive. In addition to synthetic ammonia, nitrogen is usually used as a protective gas for metallurgy, chemicals, coal, food, medicine, electronics, magnetic materials, transportation, heat treatment, tires, thermoelectricity, aviation and other industries. In many areas that are easy to oxidize, nitrogen requires nitrogen protection during the production, reaction, transportation, and storage of these products.
