Definition of high-purity oxygen
Oxygen is one of the components of air, colorless, odorless and tasteless.
Oxygen is denser than air. Under standard conditions (℃ and atmospheric pressure 3 Pa), the density is .g/L.

Foreign name:
, high-purity oxygen, detailed introduction to the use of high-purity oxygen
). In the metallurgical industry, high-purity oxygen is blown during the steelmaking process, and the oxygen mixes with carbon, phosphorus, sulfur, silicon, etc. It initiates an oxidation reaction, which not only reduces the carbon content of the steel, but also helps remove impurities such as phosphorus, sulfur, and silicon. Moreover, the heat generated during the oxidation process is enough to maintain the temperature required for the steelmaking process. Therefore, oxygen blowing not only shortens the smelting time, but also improves the quality of the steel. When making iron in a blast furnace, increasing the oxygen concentration in the blast can reduce the coke ratio and increase output. In non-ferrous metal smelting, the use of oxygen enrichment can also shorten the smelting time and increase output
.
). In the chemical industry, when producing synthetic ammonia, oxygen is mainly used for the oxidation of raw gas, such as high-temperature cracking of heavy oil and gasification of pulverized coal, etc., to strengthen the process and increase fertilizer output.
3). Liquid oxygen in the national defense industry is the best combustion accelerant for modern rockets.
). Medical and health care: supply breathing: used in hypoxic, hypoxic or anaerobic environments, such as diving operations, mountaineering, space navigation, medical rescue, etc.
