Sulfur or sulphur is the chemical element with atomic number 16, represented by the symbol S. It is an abundant, multivalent non-metal. At normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellow crystalline solid. Chemically, sulfur can react as either an oxidant or reducing agent. It oxidizes most metals and several nonmetals, including carbon, which leads to its negatives charge in most organosulfur compounds, but it reduces several strong oxidants, such as oxygen and fluorine. In nature, sulfur can be found as the pure element and as sulfide and sulfate minerals. Elemental sulfur crystals are commonly sought after by mineral collectors for their brightly colored polyhedron shapes. Being abundant in native form, sulfur was known in ancient times, mentioned for its uses in ancient Greece, China and Egypt. Sulfur fumes were used as fumigants, and sulfur-containing medicinal mixtures were used as balms and antiparasitics. Sulfur is referenced in the Bible as brimstone in English, with this name still used in several nonscientific terms. Sulfur was considered important enough to receive its own alchemical symbol. It was needed to make black gunpowder, and the bright yellow powder was hypothesized by alchemists to contain some of the properties of gold, which they sought to synthesize from it. In 1777, Antoine Lavoisier helped convince the scientific community that sulfur was a basic element, rather than a compound. Elemental sulfur was once extracted from salt domes where it sometimes occurs in nearly pure form, but this method has been obsolete since the late 20th century. Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum. The element's commercial uses are primarily in fertilizers, because of the relatively high requirement of plants for it, and in the manufacture of sulfuric acid, a primary industrial chemical. Other well-known uses for the element are in matches, insecticides and fungicides. Many sulfur compounds are odiferous, and the smell of odorized natural gas, skunk scent, grapefruit, and garlic is due to sulfur compounds. Hydrogen sulfide produced by living organisms imparts the characteristic odor to rotting eggs and other biological processes. Sulfur is an essential element for all life, and is widely used in biochemical processes. In metabolic reactions, sulfur compounds serve as both fuels and respiratory (oxygen-replacing) materials for simple organisms. Sulfur in organic form is present in the vitamins biotin and thiamine, the latter being named for the Greek word for sulfur. Sulfur is an important part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin. Organically bonded sulfur is a component of all proteins, as the amino acids cysteine and methionine. Disulfide bonds are largely responsible for the mechanical strength and insolubility of the protein keratin, found in outer skin, hair, and feathers, and the element contributes to their pungent odor when burned.
SULPHUR 80% WDG (EIRI-0991)Major uses of elemental sulfur are as a plant nutrient and as a pesticide, particularly as a fungicide. The sulfur can be applied as an aqueous suspension; however, it is more commonly applied, particularly in its pesticidal uses, as a dust or dry powder. The sulfur is commonly subdivided to a fine particle size, typically having at least 50 weight percent passing a 200 mesh screen for nutrient uses and having 98 weight percent passing a 325 mesh screen for pesticidal uses. The grinding is done at centralized manufacturing plants and the resulting sulfur powders are bagged and shipped to distributors for sale to the ultimate consumer. Substantial difficulties are encountered in handling the sulfur because the sulfur agglomerates or cakes into hard, compact masses. This compaction of the powdered sulfur is accentuated in the normal handling and storage wherein the bags of the material are commonly stacked to heights of about 25 bags resulting in a fairly substantial compaction force being applied to the lower layers of bags.
