Chemical formula: WS₂, composed of two elements, tungsten (W) and sulfur (S), tungsten is +4 valence, sulfur is -2 valence.
Crystal structure: WS₂ has a layered crystal structure, similar to that of graphite.
Appearance and colour: It is usually a black or grey powder.
Density: WS₂ has a relatively moderate density of about 7.5 g/cm³.
Hardness: WS₂ is a relatively soft material with a low Mohs hardness of about 1 – 2.
Lubrication: Tungsten Disulfide has excellent lubricating properties due to its layered crystal structure, so it is widely used in a variety of applications requiring lubrication.
Transistors and integrated circuits: Tungsten Disulfide semiconducting properties and adjustable bandgap give it great potential for use in transistors and integrated circuits.
Optoelectronic devices: WS₂ also has many applications in optoelectronic devices. For example, WS₂-based photodetectors can take advantage of its light-absorbing properties in the infrared wavelength band to achieve highly sensitive detection of infrared light signals.
Battery electrode materials: In the field of energy storage, such as lithium-ion batteries, WS₂ is gradually attracting attention as an electrode material. the layered structure of WS₂ can provide good channels for the embedding and de-embedding of lithium ions, and at the same time, its high theoretical specific capacity also offers the possibility of increasing the energy density of the battery.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
