Nitrogen:
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.
Usage of Nitrogen:
Metal industry: metal heat treatment, powder metallurgy
Chemical industry: raw material gas, pipeline purging, atmosphere replacement, protective atmosphere, product transportation
Pharmaceutical industry: pharmaceutical packaging, pharmaceutical replacement gas, pharmaceutical nitrogen-filled packaging, transportation, Chinese herbal medicine anti-moth, anti-corrosion protection, scientific research and medical deep cryogenic and cryotherapy, etc.
Food industry: nitrogen-filled storage and preservation of fruits, vegetables, tea
Shipping industry: Nitrogen is commonly used as the driving gas for dry powder fire extinguishing systems and chlorinated hydrocarbon fire extinguishing systems.
