The use of graphene for conducting phase + glass' thick films that are screen-printed onto an alumina ceramic substrate and then heat-treated in a vacuum furnace has been studied. Quantitative microanalysis of carbon and glass elements has been carried out and the microstructure and electrical properties of the films have been examined. The film surface layer shows an increased carbon content, the current-voltage curve is linear, indicating that Ohm's law is obeyed, and resistivity decreases with increasing temperature. The temperature resistance coefficient is negative. It has been concluded that graphene can be used as a conducting phase in thick films.
