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.
Preparation of amorphous boron powder Only the United States, Germany and other countries can produce amorphous boron powder industrially. The traditional boron powder preparation process uses the magnesium thermal reduction method to prepare boron powder, using Mg as a reducing agent and B2O3as an oxidant. The boron in B2O3 is replaced by the oxidation-reduction reaction to obtain amorphous boron powder. Generally, this reaction needs to be carried out at a high temperature of about 800 ℃, and the reaction formula is B2O3+3Mg=3MgO+2B-532.3kJ. Because this reaction will release a lot of heat, the temperature of the actual reaction system is extremely high, which puts forward higher requirements for heat resistance of the reaction equipment. At high temperatures, MgO in the product will also react with excessive B2O3 in the raw material to produce MgO · B2O3, which is insoluble in acid, and impurities such as nMgO · B2O3, BxO and MgB2 may also be produced, which will affect the purity of boron powder.
Use of amorphous boron powder 1. Boron powder is mainly used in metallurgy, electronics, medicine, ceramics, nuclear, chemical, etc. It is applied in the form of a compound or added to an alloy as an additive 2. Boron powder can be used in the smelting of special alloy steel and the gas scavenger of molten steel, in the pilot pole of the pilot tube in the electronic industry, in the control rod of the atomic reactor and the high-energy rocket fuel; 3. Boron powder is an important raw material for the production of high-purity boron halide and is the raw material for the production of various borides; 4. It can replace and save a large number of precious and olefin-deficient metals; 5. Boron and its compounds can also be used as catalysts for organic chemical reactions 6. As far as its energy is concerned, boron should be non-metallic fuel. Boron powder's ignition temperature is greatly reduced due to its irregular shape and large specific surface area.
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.
