  • Glass-ceramic heating element
    Patent number: 4973826
    Abstract: Glass-ceramic heating element comprising at least a flat electric heating member which is provided on a glass-ceramic plate and can be heated to a temperature between ambient temperature and approximately 650.degree. C. forming a heat source, wherein the electric heating member is produced by depositing screen-printed layers on the surface denoted the lower surface to distinguish it from the working surface of the glass-ceramic plate, these layers having a coefficient of expansion near that of the glass-ceramic material at elevated temperatures and being capable of being heated by thermal dissipation to temperatures of about 650.degree. C., and wherein the heating member is formed from this lower surface by a first layer 21 of a material constituting an electric insulator at high tempertures, a second layer 22 of a conductive material to form the two current supply lines C.sub.1 and C.sub.
