Tungsten Disulfide (WS₂) is a compound of tungsten and sulfur, known for its excellent lubrication and friction-reducing properties. As a sputtering target, WS₂ is widely used in physical vapor deposition (PVD) processes to deposit thin films with advanced mechanical, chemical, and electronic properties.
Properties:
High Temperature Resistance:Tungsten Disulfide has excellent thermal stability and can function at temperatures as high as 500°C or more, which makes it suitable for high-performance applications.
Low Friction Coefficient: One of WS₂’s standout features is its extremely low friction coefficient, making it a highly effective material for reducing wear and prolonging the life of components.
Layered Structure: Tungsten Disulfide has a hexagonal layered structure, which allows for easy shearing between layers, contributing to its lubricating properties and making it an ideal material for tribological applications.
High Corrosion Resistance: WS₂ also offers good resistance to oxidation and corrosion, adding to its longevity in harsh environments.
Applications:
Lubrication Coatings: WS₂ is highly regarded for its solid lubricating capabilities, especially under extreme conditions of high temperature and pressure. WS₂ thin films are commonly deposited on surfaces to reduce friction and wear in mechanical parts, making it ideal for aerospace, automotive, and industrial applications.
Semiconductors: WS₂ is also gaining attention in the semiconductor industry, where it is used in the production of 2D materials and thin films for transistors and other electronic components. Its layered structure offers unique electrical properties similar to other transition metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS₂).
Optoelectronics: WS₂ thin films are used in optoelectronic devices due to their bandgap and photoluminescent properties, making them suitable for sensors, photodetectors, and solar cells.
In sputtering targets, the purity, density, and microstructure of WS₂ are critical in determining the quality of the deposited thin films. High-purity WS₂ sputtering targets are widely used for producing uniform and defect-free coatings in advanced manufacturing processes.
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.
