Main Component: W₂B The main component of W₂B targets is the W₂B compound, which consists of tungsten (W) and boron (B), with tungsten having an average valence of approximately +2 and boron -2.
Crystal structure: W₂B has a tetragonal crystal structure.
Appearance and morphology: Tungsten Boride targets are generally in the form of blocks or discs, and their colour is usually grey or dark grey.
Density: 16 – 17 g/cm³.
Hardness: about 7 – 8.
Thin film deposition: Tungsten Boride targets are widely used for thin film deposition in electronics and semiconductor manufacturing. W₂B is deposited on the surface of semiconductor chips, circuit boards or electronic components by physical vapour deposition techniques such as magnetron sputtering or ion beam sputtering.
Field Emitting Materials: The electron-emitting properties of W₂B allow it to be used as a field-emitting material. By depositing W₂B films on the substrate, materials with good field emission properties can be manufactured for use in fields such as electron microscopy and flat panel displays.
Thermoelectric materials:Tungsten Boride is also valuable for research in thermoelectric conversion. Its unique electrical and thermal properties make it possible for W₂B to be used as a thermoelectric material in heat-to-electricity conversion devices to convert waste heat into electricity and improve energy efficiency.
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.
