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.

Abstract: An in-situ process for synthesizing highly pyrophoric foam materials using metal and carbon precursors wherein the precursors serve as foaming and activating agents to disperse and lock nano-sized metal particles within a rigid porous carbon matrix. The resulting carbon matrix is also pyrophoric.

Abstract: A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.
