What is amorphous boron powder? Amorphous elemental boron is more active in chemical properties than crystalline elemental boron. Crystalline boron is very hard and often used to replace diamonds to make cutting tools or drill bits. A small amount of boron is added in the metal smelting process; on the one hand, it is used as a deoxidizer to prevent metal oxidation at high temperatures; On the other hand, it forms alloys and improves the properties of metals. Amorphous boron powder is an important energy material. As a solid fuel in the composite solid propellant, boron has a calorific value of more than twice that of carbon, about twice that of aluminium, and more than that of magnesium. Its volumetric calorific value is almost three times that of carbon-hydrogen fuel, and its density is slightly lower than that of aluminium. It has the highest volumetric calorific value. In terms of its energy, boron should be the best non-metallic fuel. And amorphous boron is irregular in shape; The large specific surface area greatly reduces the ignition temperature.
Preparation of amorphous boron powder The molten salt electrolysis method is the preparation of simple boron by electrolysis of boron compounds under high-temperature molten salt conditions. The most prominent problems of electrolytic preparation of boron powder are the difficult solution of electrode materials, low yield and high energy consumption. The metal thermal reduction method is the reduction of boron oxide by magnesium powder at a high temperature to prepare coarse boron. Although the metal thermal reduction method is mature in technology and large in output, the product purity is low, and the particle size distribution is uneven. A large amount of hydrochloric acid needs to be used in the subsequent treatment process; the by-products produced have low added value, strong corrosion effect on equipment and serious pollution.
Measurement of combustion heat of amorphous boron powder Boron has become the preferred high-energy component additive due to its high volume calorific value. To measure the combustion heat of boron powder more accurately, an oxygen bomb calorimeter was used, and SQ-2 was used as the combustion aid. The effects of the quality, shape and oxygen pressure in the oxygen bomb on the combustion heat test results of boron powder were studied through experiments.
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.
