Properties of Amorphous Boron B Powder :
The chemical properties of amorphous elemental boron are more active than crystalline elemental boron. Crystalline boron is very hard, and it is often used instead of a diamond to make cutting tools or drill bits. A small amount of boron is added to the metal smelting process. On the one hand, it is used as a deoxidizer to prevent the metal from oxidizing at high temperatures. On the other hand, it forms an alloy to improve the performance of the metal.
Product features of Amorphous Boron powder:
Amorphous boron powder is a vital energy material. It is used as a solid fuel in composite solid propellants. The calorific value of boron is more than twice that of carbon, about twice that of aluminum, and more than twice that of magnesium. In terms of its energy, boron should be the best non-metallic fuel. Due to its irregular shape and large specific surface area, amorphous boron significantly reduces its ignition temperature.
