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.
Use of amorphous boron powder It can interact with oxygen, nitrogen, sulfur, halogen and carbon at high temperatures to generate various compounds. It can directly combine with many metals to generate metal borides and react with organic compounds to generate organic boron. It is used for surface coating materials, such as semiconductor industry, powder metallurgy additives and thermal spraying.
Measurement of combustion heat of amorphous boron powder To improve the accuracy of the combustion heat value of boron powder measured by the combustion-supporting method and explore the rules and principles of the selection of combustion aids, four substances commonly used in the field of boron-containing propellant development, namely benzoic acid, 90 square tablets, magnesium powder, and a rocket propellant test standard powder, were selected as combustion aids. The combustion heat of 95-grade amorphous boron powder was measured in the GR3500 oxygen bomb calorimeter by dry method and wet method, and a comparative experimental study was carried out. The results showed that: without combustion aids, The combustion heat of boron powder was directly tested, and the ignition failed; The combustion efficiency of boron powder is different with different combustion aids. The analysis shows that the selected combustion aids should have the characteristics of easy ignition, high heat value, high combustion temperature, and low gas formation rate. At the same time, the combustion rate should match the boron powder, and the chemical properties should have good compatibility with the boron powder. In addition, in the mixed sample, the closer the combustion aids and boron powder are combined, the more uniform the mixing is and the more effective the combustion support is. Compared with dry mixing, the combustion efficiency of boron powder is higher when the sample of solid grain made by wet mixing is used to test the combustion heat value of boron powder.
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.
