Nature Education Knowledge 3 10 Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most organisms. This article explores how nitrogen becomes available to organisms and what changes in nitrogen levels as a result of human activity means to local and global ecosystems.
Aa Aa Aa. Figure 1: Major transformations in the nitrogen cycle. Nitrogen Fixation. Figure 2: Chemical reaction of nitrogen fixation. Nitrogen is used during the manufacturing process to create an inert atmosphere to prevent oxidation that may lead to electrical failure.
Nitrogen is used to remove impurities during the manufacturing process of stainless steel. One of the top qualities of stainless steel is corrosion-resistant and is a result of nitrogen gas being introduced into the manufacturing process. Follow Us On. Serving Science Globally!
One of the most important nitrogen compounds is ammonia NH 3 , which can be produced in the so-called Haber-Bosch process, in which nitrogen is reacted with hydrogen. The colorless ammonia gas with a pungent smell can be easily liquefied into a nitrogen fertilizer.
In fact, about 80 percent of ammonia that is produced is used as fertilizer. It is also used as a refrigerant gas; in the manufacture of plastics, textiles, pesticides and dyes; and in cleaning solutions, according to the New York Department of State. The nitrogen cycle, in which atmospheric nitrogen is converted into different organic compounds, is one the most crucial natural processes to sustain living organisms. During the cycle, bacteria in the soil process or "fix" atmospheric nitrogen into ammonia, which plants need in order to grow.
Other bacteria convert the ammonia into amino acids and proteins. Then animals eat the plants and consume the protein. Nitrogen compounds return to the soil through animal waste. Nitrogen is even used in many electronics or the manufacturing of them. It is used in the internal workings of many computers and helps to prevent them from overheating and burning themselves up after hours of continuous use. It is widely used in the fire suppression systems for Information Technology IT equipment since normal water and extinguisher methods are not usually or effective in these types of situations.
Nitrogen is also used X-ray detectors and other electronics used in the medical field! Nitrogen has proven to be a versatile and useful gas and it has even found its place with applications such as a purging gas in the steel industry.
It is used to help remove impurities during the production of stainless steel and is part of the reason for the clean corrosion resistant qualities of the steel. It also finds application serving as what is known as a shielding gas, which helps to safeguarding technological processes against the corrosive process of oxidation.
