| An electrothermal slurry are prepared by micro-silver powder, graphite powder, carbon black, filler (talc, lithopone, alumina powder) and polymer resin adhesive. The electrothermal slurry was prepared by mixing together 2% silver powder (average particle size less than 1.5 μm), 67% graphite powder, carbon black and filler, 31% polymeric resin adhesive. Then the slurry was adhered to the phenolic resin plate and solidified in room temperature. The electrothermo film showed low resistivity and good adhesion. And it can be used as heating piece for light-weight electric heater. |
