the inorganic compound of magnesium and boron with the formula MgB₂

Magnesium diboride (MgB₂) is a hexagonal intermetallic compound with a superconducting transition temperature of approximately 39 K, ranking among the highest critical temperatures of all metallic-compound superconductors, with practical operating temperatures of 20–30 K. Its alternating layers of magnesium and boron offer abundant resources, low cost, high electrical conductivity and ease of synthesis and processing, and it can be manufactured into thin films and wires. BoronHub supplies micron-grade spherical magnesium diboride powder with 99.9% purity and particle sizes covering 1–5 μm and 5–10 μm; nano-scale, ultra-fine and spherical powders can also be customised on request. The material is compatible with vacuum sintering, magnetron sputtering and powder metallurgy, and is widely used in superconducting materials, electronic ceramics, conductive composite materials and cutting-edge scientific research.
