Description

The direct elementary reactions among the first and second row elements often yield novel super hard, high energy density, and wide band-gap optical materials. The reactions of oxygen and nitrogen with boron and carbon have been investigated at high pressures and temperatures by using an integrated technique of diamond-anvil cell, laser-heating, x-ray diffraction, Raman spectroscopy. A wide range of products has been synthesized and characterized in-situ at high pressures, including {alpha}-CO{sub 2}, B{sub 2}0{sub 3}-I,B{sub 2}0{sub 3}-II, c-BN, h-BN, h{sup `}-B, amorphous carbon nitrides. The elementary reactions occur exothermically and result in highly polycrystallized products with an exception in carbon-nitrogen ... continued below

The implication of the elementary reactions to energetic materials applications is discussed.
