Product Introduction
AMORPHOUS BORON POWDER widely used in the boron powder market is mainly crude boron with a high impurity content produced by the magnesian thermal reduction method. The magnesian thermal reduction method is simple, has a high yield, and relatively low cost. Because standards vary greatly across different fields, the definition of “amorphous boron powder” is not entirely consistent.
Amorphous boron 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.
Product Features
- Based on the specific gravity of boron, it is divided into amorphous boron and crystalline boron. Amorphous boron has a specific gravity below 1.73 g/cm³.
- The widely used amorphous boron is formed by reduction at around 1000℃, of which 60% is α-rhombic crystalline boron,And 40% is amorphous boron, a mixture of crystalline and amorphous.
- Due to its small particle size and uniform distribution, amorphous boron has high activity.

Applications:

1. Amorphous boron powder with a boron content of 95-99% possesses high mass heat and volumetric heat, resulting in a large specific impulse. It is a high-quality material for rocket propellants and explosives.
2. Boron powder with a boron content of over 99% is an electronic material that acts as a deoxidizer, antioxidant, and catalyst.It plays a crucial role in semiconductor manufacturing, influencing the conductivity and crystal structure of semiconductors, thereby affecting the performance and reliability of components. It is widely used in high-end products requiring high boron purity, such as electronic materials and semiconductor diffusion.
3. Amorphous boron powder with a purity of 99.9% is used in the production of solar silicon wafers as a substrate dopant for P-type silicon wafers and for boron emitter diffusion in N-type silicon wafers.
4. High-purity boron powders of 5N and 6N can be used as dopants in P-type semiconductors to alter their conductivity, enabling the production of high-purity silicon wafers.
