This application enables data on many gas molecules to be accessed rapidly.You can search on a raw chemical formula, chemical name or UN transportation code. The values displayed on this page are extracted from the literature and the proprietary current AIR LIQUIDE Group data. A COLD RESERVE: IT CAN BE LIQUEFIED BY COOLING IT AT -196°C. Nitrogen was discovered in 1772 by Daniel Rutherford who called it noxious air or fixed air. But it was Lavoisier who, in 1786, isolated it. The name nitrogen comes from Latin nitrogenium, where nitrum (from Greek nitron) means "saltpetre", and genes means "forming".Nitrogen is mainly found in the atmosphere, where it accounts for 78 % by volume of the air we breath.
Nitrogen is used both as an inert and a vector gas to ensure safe processes and to maintain product quality. It is typically used for blanketing coal during storage and transport to the blast furnace, for equipment purging and stirring melt in the converter and ladles. Nitrogen provides the inert atmosphere that prevents undesirable reactions between liquid metal and the surrounding atmosphere. Applications also include slag splashing.In the production of nickel and copper, nitrogen is injected through lances or tuyeres into molten baths to provide metal stirring. It is also used for cooling. Nitrogen is also used for blanketing of lead baths to protect metal from oxidation. Others applications include degassing, removal of inclusions and injection of Al 2 O 3 into cryolite baths and refer to primary aluminium processing.For any technical information on this topic, a quotation....
Nitrogen (N₂) is a molecule composed of two atoms. It’s the main constituent of the atmosphere since it represents 78% of the air we breathe in terms of volume. It is essential as it dilutes oxygen which would reach such high concentration without it that it would be harmful for human beings.It was discovered in 1772 by Daniel Rutherford .To produce nitrogen, it is necessary to separate it from the other components of air, notably from oxygen (21%). Air can be liquefied at an extremely low temperature (of around -190°C). Its components (nitrogen, oxygen, noble gases) are then separated through distillation .Another method consists in forcing air through polymer membranes in the shape of hair-thin hollow tubes.

Universal Industrial Gases, Inc...Nitrogen N2 Properties, Uses, Applications - Gas and Liquid Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is nonflammable and it will not support combustion. Nitrogen gas is slightly lighter than air and slightly soluble in water. It is commonly thought of and used as an inert gas; but it is not truly inert. It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur. Nitrogen compounds are formed naturally through biological activity. Compounds are also formed at high temperature or at moderate temperature with the aid of catalysts.
