Application of amorphous boron powder in various industries

wallpapers Tech 2020-05-29
Amorphous boron powder is an odorless, dark brown powder that is stable in air at room temperature. It can be oxidized when heated to 300 ° C and ignite when it reaches 700 ° C. As a boron exceptional chemical product, it is widely used in metallurgy, synthesis, and aerospace fields. Commonly used as a deoxidizer, initiator of automobile airbag, igniting agent of rocket launching fuel, etc.

The chemical properties of amorphous elemental boron are more active than crystalline elemental boron. Since crystalline boron is hard, it is often used instead of a diamond to make cutting tools or drill bits. A small amount of boron is added during the metal smelting process. On the one hand, it acts as a deoxidizer to prevent the metal from oxidizing at high temperatures; on the other hand, it forms an alloy to improve the mechanical properties of the metal. For example, boron copper is used to making control rods for atomic reactors.
In October 2003, Chinese scientists successfully introduced amorphous boron powder into the ignition agent of rocket-launched fuel. This initiative made the military application of amorphous boron powder in China a reality. Amorphous boron powder will become a critical energy material, and its use in composite solid fuels has long been paid attention to. As a solid fuel, the calorific value of boron is more than double that of carbon, about twice that of aluminum, and more than twice that of magnesium. Its volume calorific value is almost three times that of hydrocarbon fuel, and its density is slightly lower than that of aluminum. The highest volume calorific value, in terms of energy, boron should be the best non-metallic fuel. And the amorphous boron has dramatically reduced its ignition temperature due to its irregular shape and large specific surface area.

Trunnano is one of the world's largest manufacturers of amorphous boron powder. If you are interested in boron powder, please contact Leo Manager, email: brad@ihpa.net.
