1. Nitrogen can be used in the chemical industry for synthesis = cyanide and other production. Pure nitrogen is used as a protective gas and lamp filling gas to prevent oxidation, volatilization and flammable substances. Liquid nitrogen is mainly used as a cold source for deep freezing treatment of instruments or machine parts and quick freezing of food. It is also used for low temperature micro-grinding and electronics industry. 2. Used in metal smelting, chemical industry, mechanical processing and other industries. 3. Used in chemical fertilizer, medicine, animal husbandry, refrigeration and electronics industry. 4. Used for , synthetic , explosives, etc. 5. Used in electrical appliances, food packaging filling gas, semiconductor device preparation process of thermal oxidation, epitaxial diffusion, chemical vapor deposition, etc., can also be used in gas chromatograph 6. It is used for extraction and freezing of rare gases, cryogenic treatment of instruments or parts, etc. 7. It can be used as air and oxygen dispersant. 8. Nitrogen can also be used as a refrigerant, and can be used as a direct refrigerant for the rapid freezing of food Chemicalbook; Packaging gas (to replace the residual air in the packaging container to extend the shelf life). Nitrogen is often referred to as an inert gas and is used in certain inert atmospheres for metal treatment and in light bulbs to prevent arcing, but it is not chemically inert. It is an essential element in plant and animal life and is a component of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear resistant metals. A small amount of nitrogen in steel inhibits grain growth at high temperatures and also increases the strength of some steels. It can also be used to produce a hard surface on steel., nitrate, cyanide, etc. In the manufacture of explosives; Filled high temperature thermometer, incandescent bulb; Form inert material to preserve material for use in drying boxes or glove bags. Liquid nitrogen in food freezing process; Used as a coolant in the lab.
