In order to meet the technical requirements for the rapid and maneuvering purpose of a new generation of missile hypersonic aircraft in the future, it is necessary to develop light weight, small size, fast speed, long range, and good maneuverability power devices, and solid rocket ramjets and their combinations Propulsion technology is a good choice to solve this problem. Fuel-rich propellants used in solid jet engines have also been rapidly developed. Boron powder has become a fuel-rich propellant fuel with development potential due to its high mass calorific value and volumetric calorific value, so it has attracted the attention of domestic and foreign researchers.

Aluminum is often used as a fuel in energetic formulations, and is widely used in propellants, explosives and pyrotechnic formulations. The heat of combustion of boron is almost twice that of aluminum and is considered to be the best substitute for aluminum.
Adding a small amount of boron powder to the aluminum-containing fuel air explosive can increase the overall energy level of the explosive.

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. Very 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.
Tests have shown that the energy release of boron powder in the detonation process can increase the duration of underwater bubble energy and air burst fireball.
Among energetic materials, boron/aluminum composite powder is widely used.
