Aluminium Silicon Oxide Core Shell Nanoparticles

Aluminium Silicon Oxide, with a high enthalpy of combustion, is commonly used in rocket propellant formulations. However, aluminum oxide may rapidly form when aluminum surfaces are exposed in air, especially superfine aluminum particles. Due to their chemical and thermal durability, silica coatings are of interest for protection of materials against oxidation, such as iron, carbon fibers and Co.
