What is amorphous boron powder? Amorphous boron powder, also known as monomer boron, is a grey-black or brown amorphous powder. Its chemical properties are relatively active, odourless and odourless. It is stable in the air and at room temperature. It is oxidized when heated to 300 ℃ and burns when it reaches 700 ℃. The flame is red when burning, and the flame of micro-gasified boron is green. Boron is insoluble in water, hydrochloric acid, ethanol, ether, sulfuric acid, nitric acid and molten metal. It can be dissolved in a cold concentrated alkali solution and decomposed into hydrogen; It is oxidized to boric acid by concentrated nitric acid and concentrated sulfuric acid. Boron can interact with oxygen, nitrogen, sulfur, halogen and carbon at high temperatures. Boron can also be directly combined with many metals to form metal compounds and can also react with organic compounds to form compounds directly associated with boron and carbon or compounds with oxygen between boron and carbon. Monomer boron is in a special position in the periodic table to divide elements into metal and non-metal boundaries; it is an element with dominant non-metallic properties, a strong negative charge, a small atomic radius, and a full nuclear charge, and non-metallic properties similar to silicon. Its density is 2.35g/cm3, hardnessis 9.3; specific gravity is 2.33-2.45, melting point: is 2300 ℃, and boiling point: is 2550 ℃.
Use of amorphous boron powder Chinese scientists have successfully launched amorphous boron powder into the ignition agent of rocket launch fuel. This move has made the application of amorphous boron powder in China's military a reality. Amorphous boron powder will become an important energy material, and its application in composite solid fuel has long been paid attention to. As a solid fuel, boron's calorific value is more than twice that of carbon, about twice that of aluminium, and more than twice that of magnesium; its volumetric calorific value is almost three times that of hydrocarbon fuel, its density is only slightly lower than that of aluminium, and it has the highest volumetric calorific value. In terms of its energy, boron should be the best non-metallic fuel. Moreover, amorphous boron greatly reduces its ignition temperature due to its irregular shape and large specific surface area.
Preparation of amorphous boron powder The amorphous boron powder is prepared by thermal reduction reaction of boron anhydride powder and magnesium particle with a mass ratio of 3:1 at a temperature of 800-1100 ℃, and then washed, dried and sieved to obtain amorphous boron powder; The amorphous boron powder prepared by this process has high purity, up to 97-98%, small and uniform particle size, and good combustibility. It can be used for solid ramjet and clean, smokeless propellant.
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.
