Sulfur is a chemical element with symbol S and atomic number 16. It is an abundant, polyvalent, odorless and tasteless non-metal. Mostly it is in form of yellow crystals in sulfide and sulfate inorganics. Sulfur is produced as byproduct of oil, gas and petrochemicals. Considering various parts of gas refineries set up, its annual production amount is increasing. It was known as brimstone (burning stone). Sulfur is one of the most essential raw materials in chemical industry, which is utilized as agricultural phosphate fertilizers. It can be attached to metal and produce various inorganic sulfides such as galena (lead sulfide), pyrite (iron sulfur), chalcocite (copper sulfide), Sphalerite (zink sulfide).
Sulfur is one of the primary mixtures in manufacturing phosphate fertilizers as a fungicide. Other applications are in the plastics industry, synthetic and paper products, paints, non-ferrous metal products, oil compounds refinery, steel and iron products, water treatment and soil, animal micronutrients and in the road used as an additive to recovery asphalt, sulfur concrete, sulfur polymer cement, roofing material, floor and so on. This element is used for industrial production (such as H2SO4), sulfuric acid for producing batteries, and heating rubber. Sulfates are also used in washing paper and dried goods in addition to making matches and fireworks. Ammonium thiosulfate or Sodium as a fixing agent is used in photography. Magnesium sulphate can be utilized as anti-dry agent, which is a herbal magnesium supplement.
