95-97% Amorphous Boron Powder(B powder) 3um 5um
95-97% Amorphous Boron Powder(B powder) 3um 5um is an amorphous element, elemental boron. Our company uses a magnesothermic reduction method combined with multiple special purification processes to produce high-purity amorphous boron powder. Amorphous boron powder possesses high gravimetric heat, volumetric heat, and reactivity. It is widely used in solid fuel-rich propellants, as a deoxidizer, antioxidant, and catalyst in the electronics industry, and plays a vital role in new materials and semiconductor fields. The particle size of amorphous boron is less than 3µm; some larger particles require secondary processing.
