Our amorphous (non-crystalline) boron powder is produced via high-temperature reduction processes, delivering a dark brown to black powder with a purity range of 90% – 95%+ (customizable up to 99%).
Unlike crystalline boron, the amorphous form offers significantly higher surface area and chemical reactivity, making it the preferred choice for energetic materials, metallurgical alloying, and nuclear applications.
Key features:
High volumetric combustion heat (~30 kJ/cm³)
Low oxygen & moisture content
Controlled particle size (D50 from submicron to 10+ µm)
Excellent ignition sensitivity
