Amorphous boron powder is black or dark brown powder, it’s stable in the air at room temperature, and it is widely used in metallurgy, synthesis, aerospace and other fields.
Amorphous Boron Powder Properties
Amorphous boron powder is black or dark brown powder. When it is oxidized in the air, the formation of a diboron trioxide film prevents the internal boron from continuing to oxidize. Amorphous boron powder can react with fluorine at room temperature and is not corroded by hydrochloric acid and hydrofluoric acid aqueous solutions.
Boron is insoluble in water. Powdered boron is soluble in boiling nitric acid and sulfuric acid, as well as most molten metals such as copper, iron, manganese, aluminum and calcium. Amorphous boron is chemically active, its powder and air can form an explosive mixture.
Amorphous Boron Powder Applications
High-purity boron powder is mainly used in metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry and other fields, and can also be used as a high-energy fuel.
Amorphous boron powder can be used as an alloy component in smelting metals to form alloys and improve the mechanical properties of metals. Sometimes it can replace scarce metals. Boron powder can also be used to make various borides and additives for various materials, such as ceramic additives.
High-purity boron powder is rich in fuel propellant and can be used as the preferred charge for missiles and ramjet engines, and can meet the high-speed, long-range, and small-volume performance requirements of air-to-air missiles. Amorphous boron powder can also be used as a high-energy fuel, the ignition point of boron powder is low, and boron is a good non-metallic fuel.
