| Description | Oxygen, chemical formula O2, type the amount of 32.00, colorless and odorless gas, oxygen most common elemental form. Melting point -218.4 ℃, the boiling point of -183 ℃. Easily soluble in water, 1L of about 30mL of dissolved oxygen. In about 21% oxygen in the air. LOX is sky blue. Solid oxygen is blue crystals. At room temperature is not very lively, with many substances are difficult to effect. However, at high temperatures is very lively, direct combination with a variety of elements, which is second only to fluorine electronegative oxygen atoms related. |
| Usage | Smelting Process: Blowing in the steelmaking process with high purity oxygen, carbon, and oxygen will phosphorus, sulfur, silicon, etc. from the oxidation reaction, which not only reduces the carbon content of the steel, but also help remove phosphorus, sulfur, silicon and other impurities . And the heat generated during the oxidation process is sufficient to maintain the desired temperature of steel, and therefore, not only shorten the refining oxygen blowing time and improving the quality of steel. When the blast furnace to improve blast oxygen concentration can tar ratio and increase production. In the non-ferrous metal smelting, the use of oxygen enrichment can also shorten the refining time to increase production. Chemical industry: in the production of ammonia, oxygen gas is mainly used for oxide materials, in order to strengthen the process, improve fertilizer production. As another example, high temperature cracking of heavy oil, pulverized coal gasification and the like. Defense Industry: liquid oxygen oxidizer is the best of modern rocket in supersonic aircraft also need oxygen as the oxidant, combustible material after impregnation with a strong explosive liquid oxygen, liquid oxygen can be made explosives. Healthcare: supplied breathing: for hypoxia, hypoxia or oxygen-free environment, such as: diving, climbing, high-altitude flight, astronauts, medical rescue isochronous. Other aspects: it itself as accelerant and acetylene, propane and other flammable gases used in conjunction to achieve the effect of welding and cutting metals industries, particularly machinery enterprise is widely used as a cut is also very easy to use, is the preferred A cutting method. |
| Precautions | 1, the excess oxygen will promote life aging. 2. Inhalation: rapidly from the scene to fresh air. Maintain airway patency. If not breathing, give artificial respiration immediately. Medical treatment. 3, fire fighting methods: water cooling containers to keep prevent heat explosion, sharp contribute to the fire. Quickly cut off the gas supply, water spray protection officers off the gas source, and then select the appropriate extinguishing agent fire causes. |
