Gas Introduction
Nitrogen is a simple substance formed from the element nitrogen, with the chemical formula N ₂. At room temperature and pressure, it is a colorless and odorless gas that can only react with hydrogen to produce ammonia under high temperature, high pressure, and catalytic conditions. In the case of discharge, it can combine with oxygen to produce nitric oxide; Even active metals such as Ca, Mg, Sr, and Ba can only react with them when heated.
Nitrogen is the 30th most abundant element on Earth. Considering that nitrogen accounts for 4/5 of the atmospheric volume, which is over 78% of the atmosphere, almost unlimited amounts of nitrogen can be used. Industries often use the method of fractional distillation of liquid air to obtain large amounts of nitrogen gas.
