How is amorphous boron powder produced?

What is Amorphous boron powder?
Amorphous boron powder is a black or brown amorphous powder with a melting point of 2150 and a boiling point of 3680. Its chemical properties are relatively active, and it is stable in air and room temperature. When it is heated to 300, it will be oxidized, and when it reaches 700, it will catch fire. The boron flame with slight gasification is green. The content of Boron in the crust is 0.001%. Boron is a black or silver-gray solid. Crystal boron is black, its hardness is second only to that of diamond, and its texture is brittle. Boron was named Boron, and its name came from Arabic, which originally meant "flux." It shows that the ancient Arabs knew that borax has the ability to melt metal oxides and is used as a flux in welding.
At high temperatures, it can interact with oxygen, nitrogen, sulfur, halogen, and carbon to generate various compounds, can also directly combine with many metals to generate metal borides, and can also react with organic compounds to generate organic boron. It is used as surface coating materials in the semiconductor industry, powder metallurgy additives, and thermal spraying.
More about Amorphous boron powder
Mr10.81 ρ=2.37g/cm3 (amorphous); 2.34 ~ 2.46 g/cm3 (crystal). Melting point is 2177 ~ 2301; Boiling point is 2550 ~ 2658.
Boron has the largest volume of heat, and its weight heat is second only to beryllium. Slightly soluble in nitric acid and insoluble in water.
Amorphous boron is chemically active. Powder and air can form an explosive mixture. Preparation of indefinite boron by reduction of boron anhydride with magnesium.
Used for solid ramjet and clean, smokeless propellant.
Elemental boron is a black or dark brown powder, which prevents the internal boron from further oxidation due to the formation of boron trioxide film when it is oxidized in the air. It can react with fluorine at room temperature and is not corroded by hydrochloric acid and hydrofluoric acid aqueous solution. Boron is insoluble in water, while powdered boron is soluble in boiling nitric acid and sulfuric acids and most molten metals such as copper, iron, manganese, aluminum, and calcium.
preparation method of Amorphous boron powder
There are two main techniques to obtain pure boron powder: via gas and magnesiothermic reaction. The first technique uses hydrogen gas to reduce gaseous boron trichloride (BCl3), whereas the latter uses a combination of heat and magnesium to reduce the boron trioxide (B2O3) to elemental boron.
Price of Amorphous boron powder
Amorphous boron powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Amorphous boron powder. A large amount of large amount will be lower. The price of Amorphous boron powder can be found on our company's official website.
