Amorphous Boron powder has physicochemical properties
Mr10.81
Boron has a bandgap between 1.50 and 1.56eV which is greater than silicon or germanium. It can transmit infrared radiation. While boron can conduct electricity well at high temperatures, it is less efficient at room temperature. Boron, which is also heavier than beryllium, has the highest volume of heat. It is slightly insoluble, but not insoluble, in nitric and water.
The formation and preservation of boron trioxide films is important to prevent further oxidation. It reacts well with fluorine at room temperatures and is not corroded or effected by hydrochloric and hydrofluoric acids aqueous solutions. Boron is insoluble when it comes into contact with water. However, in powder form, it can be dissolved in boiling nitric acid and sulfuric acid.
Amorphous Boron It is chemically active. Amorphous Boron Powder can make an explosive mixture with oxygen.

Borane cracking (molten salt electrolysis), hydrogen reduction, thermal degradation, magnesium thermal reduction and thermite removal
Magnesium thermal-reduction method: Use B2O3 for the raw material and Mg powder for the reducing agent. Self-spreading magnesium thermal reduction reaction is used to get reduction products. The ultra-fine amorphous powder of boron is obtained by hydrochloric Acid leaching.
Amorphous Boron powder:
Amorphous boron dust Many advantages include a large specific surface, high calorific value, and ease of transport. It is used widely in many fields, such as military and aviation as well as aerospace and automobile.
Amorphous boron dust This is the main use of Boron in high-energy fuels, boroncontaining functional ceramics and space technology. Boron is a good degassing agent for steelmaking because it reacts with nitrogen and oxygen at high temperature. Boron fiber is very strong and composite materials made out of epoxy resin are used to make rockets, missiles and aircraft. It is also used in the atomic energy sector as a protective substance.
