Description:
Nano boron powder is a high-energy combustion component. The volumetric calorific value (140kg/cm3) and mass calorific value (59kg/g) of elemental boron are far greater than those of other single-molecule energetic materials such as magnesium and aluminum.
And boron powder is a good fuel, especially nano boron powder has a higher combustion efficiency, so adding nano boron powder to explosives or propellants can significantly increase the energy of the energetic material system.
Boron powder has a high mass calorific value and volume calorific value, and it is a metal fuel with good application prospects, especially in the field of oxygen-poor solid propellants. It is currently the only solid ramjet that can achieve a specific impulse of 10kN·s. Propulsion energy above kg-1, so boron is one of the most suitable fuels in oxygen-lean propellants.
In order to improve the activity of boron powder, B/X (X=Mg, Al, Fe, Mo, Ni) composite particles are also prepared for use in propellants.
Storage Condition:
Boron Powder should be sealed and stored in a dry, cool environment. It should not be exposed to the air for a long time to prevent agglomeration due to moisture, which will affect the dispersion performance and use effect. In addition, avoid heavy pressure and avoid contact with oxidants.
