Vanadium Diboride Powder (VB2)

Vanadium diboride powder is a material with excellent physical and chemical properties. It has high melting point, high hardness, and excellent conductivity and thermal conductivity, which can maintain stability in extreme environments such as high temperature and metal smelting. This powder can not only be used as a fine ceramic raw material for producing wear-resistant and semiconductor thin films, but also as a new type of energy material with large discharge capacity as an alkaline battery electrode material. In addition, vanadium diboride powder has a wide range of applications in conductive ceramic materials and other fields. However, it should be noted that the dust of vanadium diboride may cause irritation to the skin and eyes, so appropriate protective equipment should be worn when using and operations should be carried out in well ventilated areas.

Where is VB₂ Powder Commonly Used?

VB₂ powder is a material of choice in applications requiring extreme durability, chemical stability, and multifunctionality:

  • Aerospace & Defense Components
    Integrated into UHTC matrices (e.g., with ZrB₂ or SiC) for thermal protection systems, hypersonic vehicles, and nozzles.

  • Refractory Coatings
    Applied in plasma spray or thermal barrier systems to protect high-temperature surfaces from oxidation and wear.

  • Conductive Ceramics & Cermets
    VB₂’s conductivity and thermal shock resistance make it ideal for advanced composite ceramics in electronics or structural supports.

  • Sputtering Target Feedstock
    Used to manufacture VB₂ sputtering targets for deposition of hard, conductive thin films.
