Improved Boron for Enhanced Combustion

Abstract

The objective of this effort was to develop a domestic commercial process for producing pure, spherical, amorphous boron particles with diameters in the range of 0.5 to 3 microns. Such particles could offer improved combustion and processing properties over present commercial boron powders when incorporated into slurry and solid fuels. The approach was to start with the Callery process for making high-purity, submicron size boron, then change process variables and add a recycle in an attempt to increase particle size. Pure, spherical particles approaching 0.1 micron were achieved. Allied-Signal EMRC provided the overall program management, boron analysis and characterization.
