The explosive properties of porous-silicon, impregnated with an oxidant, were researched. A custom porous layer structural model is used to model the pore and crystallite dimensions as a result of the electrochemical etching of porous silicon layers. A gravimetric experimental technique is used whereby the pore dimensions and specific surface area of porous regions are determined. The properties of different oxidants were investigated. The filling of the pores by the oxidant is a strong function of pore size and the type of oxidant used. The experimentally observed nano-explosive figure of merit (FOM) is a function of the effective surface area in the porous region covered by the oxidant. It was found that there is an optimum pore size for the most energetic explosion. Future applications for this new technology are proposed.
