Chemical formula: W₂B, consists of two elements, tungsten (W) and boron (B), the average valence of tungsten is about + 2 valence, boron is – 2 valence.
Crystal structure: W₂B has a tetragonal crystal structure.
Appearance: W₂B powders are generally grey or dark grey in colour.
Density values: 16 – 17 g/cm³.
Hardness characteristics: around 7 – 8.
Transistors and integrated circuits: The semiconductor properties of W₂B make it potentially useful in the field of transistors and integrated circuits.
Resistive materials: Because the resistance of W₂B varies significantly with temperature, it can be used as a temperature-sensitive resistor (thermistor) material.
Optical modulation materials: Tungsten Boride is light absorption and reflection properties allow it to be used as an optical modulation material. In the field of optical communications, it can be used to manufacture optical switches, optical attenuators and other optoelectronic devices, which can be used to regulate the on-off of the optical path or the magnitude of the light intensity by changing the optical or electrical signals.
Coatings for cutting tools and moulds: Tungsten Boride is high hardness and chemical stability allow it to be used in the manufacture of coatings for cutting tools and moulds. During metal processing, coatings can improve the wear resistance of tools and moulds and extend their service life.
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.
