Abstract

A mixture of at least one polysilane and at least one polycarbosilane is formed in the presence of a metal silicide. The mixture is formed utilizing a method that includes the step of combining the metal silicide and an alkyl halide in a reactor at a temperature of from 200°C to 600°C. The alkyl halide has the formula RX wherein R is C C alkyl and X is halo. This method forms high yield mixtures of the at least one polysilane and the at least one polycarbosilane. Additionally the mixture is time and cost effective and allows the mixture to be formed in a predictable and controlled manner. Moreover the components used in this method can be easily recycled and/or re used in other processes.
