Development of Boron Particles Ignition and Combustion

The researches on ignition and combustion of boron were reviewed, and the approach to improve the ignition and combustion performance of boron was discussed. It is shown that the difficult ignitability and low combustion efficiency of boron are caused by oxide of boron surface. Using fine diameter boron, coating boron and adding other ingredient into the boron based fuel rich propellants can increase employed efficiency of boron.
