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 ℃.
Preparation of amorphous boron powder Mix magnesium powder and boron oxide powder, magnesium nitride, calcium fluoride, manganese monoxide, alkali metal carbonate, molten salt and grinding aids, and then ball mill to make the ball abrasive; Then, under the protection of the heating reduction reaction, the gas must be cooled after the reaction to remove the surface scum and must be returned to the raw material; The ultrafine amorphous boron powder can be obtained by mixing the raw material with hydrochloric acid in the mass ratio of 1:5 to 1:10, freezing and thawing for 6 to 8 times, and then ultrasonic pickling, water washing and drying.
Application of amorphous boron powder 1. Preparation of other boride raw materials 2. Special metal products are alloy components 3. Car airbag initiator 4. Deoxidizer for oxygen-free copper smelting 5. Paint and hardener 6. Components in high-tech ceramics 7. Flux 8. Initiating explosive device additive 9. Other applications requiring high-purity boron 10. MgO-C brick additive for high-temperature steelmaking furnace.
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.
