Abstract:
1. A method for producing an electrically conductive glass, the method comprising the steps of: providing a base composition comprising a lithium carbonate powder, and a boric acid powder; adding to the base composition at least one metal salt; mixing the base composition and metal salt to form a doped base composition; melting the doped base composition to form a doped glass melt; casting the doped glass melt at approximately room temperature to yield a doped glass article; thereafter, thermally conditioning the doped glass article at a temperature of approximately the glass transition temperature (Tg) to remove residual stress; after the step of thermally conditioning the doped glass article, heat treating the doped glass article at a temperature below Tg for a time sufficient to yield a doped glass product having electrically conductive metal particles that are substantially homogeneously dispersed throughout the doped glass product, the doped glass product having an electrical conductivity of at least one order of magnitude greater than the electrical conductivity of a non-doped glass article made by the steps of melting the base composition without adding a metal salt, casting, thermally conditioning, and heat treating.
