Abstract
The invention relates to a process for forming a conductive track or coating on a substrate, comprising: applying a conductive paste to the substrate, the conductive paste comprising a solids portion dispersed in an organic medium, the solids portion comprising particles of electrically conductive material and an inorganic particle mixture comprising substantially crystalline particles of two or more different metal compounds, wherein the inorganic particle mixture includes substantially crystalline particles of a tellurium compound and is substantially lead free; and firing the applied conductive paste on the surface of the substrate with a firing profile in which the temperature of the surface of the applied conductive paste exceeds 500° C. for a period of two minutes or less. The invention further relates to a substrate having a conductive track or coating formed thereon.
