A chemical reaction heat source for use in heaters for downhole applications is provided. The heat source has a solid fuel composition that comprises thermite and a binding agent. The binding agent serves to maintain the solid form of the solid fuel composition during burning and ensure a predetermined uniform heating pattern can be provided for longer. The solid fuel composition can be provided in the form of blocks. The solid fuel composition can also be provided in the form of a plurality of fragments that, during burning, behave more like powdered thermite and can flow.

Disclosed herein are energetic compositions and methods of making thereof. A composition includes particles of a nitrogen-containing oxidizer dispersed in a polymeric binder and a bonding agent bonded to a surface of at least a portion the particles. The bonding agent disclosed is a Lewis acid.

A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 m particle size.
