#ANTIMONY SULFIDE TV#

It is used as a fining agent to remove bubbles from glass, especially in TV and laptop screens.Antimony is used as a catalyst in industrial processes.Antimony is used to make lead shot, bullets, electrical cables, and solders.For instance, it is used in alloying of lead that is used in acid batteries to improve charging features. Antimony is used to make useful alloys to increase mechanical strength and hardness.Antimony is used to make flame retardant compounds.It reacts with metals, such as silver and indium to form silver antimonide and indium antimonide. Antimony reacts with halogens and form halides with +3 and +5 oxidation states. The most commo and stable oxidation state of antimony is +5. Chemical CharacteristicsĪt room temperature, antimony does not react with air, but when heated it reacts with oxygen to produce antimony trioxide. There are four allotropic forms of antimony three metastable forms: yellow, black and explosive, and one metallic form that is stable.

It is a soft element and cannot be used to make hard objects, including coins. Physical CharacteristicsĪntimony is a shiny grey metalloid. Other countries that have reservoirs of antimony include Tajikistan, Russia, South Africa and Bolivia.

In early days, China was the biggest producer of antimony, which supply around 84% of the world share. Antimony is found in more than 100 types of minerals. In nature, it is present in the form of mineral, such as stibnite, which is its sulfide mineral (Sb 2S 3). Antimony Periodic Table ClassificationĪntimony is not very abundant element. Its symbol is Sb, which was given by Jakob Berzelius as an abbreviation for stibium. The earliest description of this element was presented by Vannoccio Biringuccio in 1540. And was given the name antimoine in French which mean “monk-killer” as in early days the alchemists were monks, and antimony was poisonous. It was named antimonium in late Greek language. It was used for cosmetic and medicinal purposes in its powdered form. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl History and DiscoveryĪntimony has been known since ancient times. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Phys.Antimony is a chemical element with symbol Sb and atomic number 51. 'First-principles study of the lattice dynamics of Sb2S3' Phys. 'Pressure-induced electronic topoalogical transition in Sb2S3' Journal of Physics: Condensed Matter, 1 (28) 015602 XRD data collected from high quality large size Sb2S3 crystals Crystals are synthesized through flux zone technique to high high crystallinity and enable exfoliation. Sb2S3 crystals measure ~0.5 cm or larger in size, rated at 99.9998% purity, and exhibit strong and sharp Raman signal, ideal environmental stability, and high crystalline order. Sb2S3 crystals exhibit optical band gap at 1.7 -1.8 eV while optical and electronic properties in the monolayer form remain unknown. The orthorhombic phase of Sb2S3 belongs to the space group Pnma (number:62) Recently, Sb2S3 has been shown to exhibit topological state transition under pressure. Sb2S3 shares striking structural and physical similarities with topological insulator Sb2Te3. Antimony sulfide is the chemical compound with the formula Sb2S3 which crystallizes in an orthorhombic space group.
