What is amorphous boron powder? Amorphous elemental boron is more active in chemical properties than crystalline elemental boron. Because crystalline boron is very hard, it is often used to replace diamonds to make cutting tools or drill bits. A small amount of boron is added in the process of metal smelting; 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 mechanical properties of metals. For example, boron copper makes control rods for atomic reactors. It is an odourless black and brown powder that is stable in the air at normal temperature. It can be oxidized to 300 ℃ and ignited when heated to 700 ℃. As a boron fine chemical product, it is widely used in metallurgy, synthesis, aerospace and other fields. It is often used as a deoxidizer, an initiator for automobile airbags, and a pilot for rocket launch fuel.
Physical and chemical properties of amorphous boron powder The relationship between temperature and crystal form of grey-black shiny crystal is: ＞ 1300 ℃ is high-temperature diamond（ β- Type); 1000~1300 ℃ is tetragonal crystal; Low-temperature rhombic crystal at 800~1000 ℃（ α- Type). Relative density 2.34~2.37. Melting point 2300 ℃, sublimation temperature 2550 ℃. Insoluble in water, hydrochloric acid, ethanol and ether. Soluble in cold concentrated alkali solution and decomposed into hydrogen. It can be oxidized into boric acid by concentrated nitric acid, sulfuric acid and aqua regia. Its chemical properties are relatively active. It is stable in air and normal temperature and is oxidized when heated to 300 ℃ and ignited at 700 ℃. The flame is red during combustion, and the boron flame of micro gasification is green. It can be mixed with oxygen, nitrogen, and sulfur at high temperatures, causing Interaction between halogen and carbon. It can directly combine with many metals to form metal borides. Reaction with organic compounds can produce - B-C - or - B-O-C compounds.
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.
