Claim:
1. Electronically conductive enamel composition comprising (i) an enamel matrix melting at a temperature in the range 600° C. to 900° C. and (ii) particles, embedded in the enamel matrix, of one or more electronically conductive materials, which are not noble metals, wherein the particles (ii) have a particle size of 700 μm or smaller and are selected from the group consisting of: (a) particles of other electronically conductive materials selected from the group comprising metallic electronically conductive materials, which are not noble metals: and (b) particles made up of a combination of carbon-based electronically conductive materials and other electronically conductive materials selected from the group of metallic electronically conductive materials, which are not noble metals; and the total concentration of the particles (ii) is in the range 9.065 vol % to 67.8 vol %, with reference to the sum of the volumes of the enamel matrix (i) and the particles (ii), wherein an electronic conductance of said enamel composition at a voltage of 100V is at least 4*10
