Elemental Boron

Elemental Boron – Crystalline & Amorphous

Elemental boron is the foundation of BoronHub’s portfolio, divided into high-purity crystalline boron and amorphous boron for distinct industrial applications.

High-Purity Crystalline Boron (4N–6N)

β-rhombohedral structure, available as grey-brown powder (>500μm) or granules (1–10 mm), with purity from 99.99% (4N) to 99.9999% (6N). It offers exceptional chemical stability, Mohs hardness of 9.3, melting point of 2076 °C, and semiconductor properties. Used in silicon wafer doping, superhard material synthesis (e.g., CBN), aerospace alloys, and high-energy fuels.

Amorphous Boron (2N–3N)

α-tetragonal short-range ordered structure, dark brown powder (>500μm). It is chemically reactive: oxidation starts at 300 °C, ignition at 700 °C, and it dissolves in concentrated alkalis with hydrogen release. Applications include rocket propellants, airbag initiators, alloy steels, boron fibers, and synthesis of boron halides and rare earth borides (e.g., LaB₆).

Customization

BoronHub offers full flexibility across purity (2N–6N), particle size (submicron to 10 mm), and crystal form (α/β). Products are vacuum-sealed in aluminum foil bags or inert-gas PTFE bottles, 12-month shelf life. Tailored specifications available for semiconductor, nuclear, aerospace, metallurgy, and fine chemical industries.
