ABSTRACT:
Amorphous boron powder is chemically passivated by treatment with certain alcohols so as to form stable borate esters on the surface so as to render the boron unreactive or compatible with hydroxyl-functional pre-polymers. The treated or passivated boron is used in the manufacture of hydroxyl-terminated poly-butadiene matrix castable solid fuels and propellants.
