GeS2 (2)

Germanium Sulfide or Germanium Disulfide GeS2, white powder, orthorhombic structure, density: 2.19 g/cm3 , melting point 800°C, molecular mass 136.77, CAS No. 145114-13-2, is a compound of Germanium and Sulfur. Dry Germanium Sulfide is stable in air. Germanium monosulfide can only be prepared from weak acidic or alkaline solution, which will dissolve again when the acidity increases. It can also react with hydrogen chloride and decompose at room temperature. High purity Germanium Sulfide GeS2 99.999%, 99.9999% 5N 6N purity, reddish-yellow, amorphous or rhomb crystal and its related compounds are synthesized by Chemical Vapor Deposition (CVD) process at low temperatures and pressures, which has great utility in solid electrolyte memory elements and other electronic devices. Germanium Sulfide GeSat Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification. 

MoS2-4

Molybdenum Sulfide or Molybdenum Disulfide MoS2, dark gray with silver gray metallic luster and odorless, CAS 1317-33-5, MW 160.07, density 4.8g/cm3, melting point 1185°C, is hexagonal crystal system. It is soluble in hot sulfuric acid and aquaregia, but insoluble in water, concentrated sulfuric acid and dilute acid. Molybdenum Sulfide MoS2 is both N-type and P-type semiconductor with an indirect band gap of 1.2 eV, and monolayer MoS2 has a band gap of ~1.9eV. Molybdenum Sulfide MoS2 is the most famous of the single layer group-VI transition metal dichalcogenide TMD family. MoS2 has been used in bulk for many years as a solid state lubricant, this is due to its low coefficient of friction in addition to its high chemical and thermal stability. But as a new two-dimensional semiconductor material, molybdenum disulfide crystal is playing an increasingly important role in semi monolayer conductor field. When MoS2 transforms from bulk to two-dimensional semiconductor by Chemical vapor deposition CVD, the band structure changes from indirect band gap to direct band gap, and the band gap width is about 1.9ev. There are more applications in the field of semiconductor devices, photoelectric field, photodetector and transistor etc. Molybdenum Sulfide MoS2 at Western Minmetals (SC) Corporation with purity of 99.99% 4N in powder, granule, lump, chunk, bulk crystal and single crystal etc is available or as customized specification, with package of polyethylene bottle or composite bag.

SNS (2)

Tin Sulfide or Tin Disulfide SnS2, dark-gray or black Crystalline powder or lump, molecular mass 182.84, density 4.5 g/cm3, CAS No.1314-95-0, boiling point 1202.34°C, is insoluble in water, hydrochloric acid and nitric acid, but soluble in concentrated hydrochloric acid HCl (decomposes), aqua regia and alkaline solution. Tin Sulfide is a compound of Tin and Sulfur by the process of vacuum smelting at high temperature and pressure and zone floating methods. Tin Sulfide or Tin Disulfide SnS2 crystal 99.995% 99.999% 4N5, 5N purity by Flux Zone growth is golden yellow crystal appearance, belongs to p-type IV-VI semiconductor with an indirect band gap of ~2.2 eV, which is of interest for use as a nontoxic, inexpensive component in heterojunction photovoltaic devices, Polymerization catalyst. Tin Sulfide SnS2 at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification.

TiS2

Titanium Sulfide or Titanium Disulfide TiS2, CAS 12039-13-3, density 3.22g/cm3, MW 112, a yellow to brown flake crystal with metallic luster, with an unpleasant odor, has diamagnetism and occurs crystal transformation at 147℃, and is ideal nonstoichiometric compound. It is stable at room temperature and stable for water, dilute sulfuric acid and hydrochloric acid, but nitric acid and concentrated sulfuric acid can separate sulfur from it, and decomposed by steam. Titanium Sulfide TiS2 single crystal or polycrystals has been synthesized by various techniques such as chemical vapor transport CVT, chemical vapor deposition CVD, atomic layer deposition ALD and wet chemical synthesis through mixing the sponge titanium with sulfur etc, it has been studied extensively for energy storage device, lithium batteries, optics, thermoelectric material application, target material and for research purpose etc. TiS2 has been considered as a degenerate, small-gap semiconductor or a semimetal owing to its high conductivity and optical absorption properties. Titanium Sulfide TiS2 at Western Minmetals (SC) Corporation with 99.9% 3N, 99.99% 4N, 99.999% 5N purity in form of powder, lump, granule, bulk crystal and single crystal etc are available, with package of vacuumed composite bag or bottle.
