Abstract
A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.
