Abstract
An electrically-conductive, thermally-insulating structure includes a thermally-insulating layer having a thermal conductivity of no more than about 3.5×10−3 W/hr·cm·°K and an electrically-conductive layer, applied to the thermally-insulating layer, which has an electrical resistivity of no more than about five ohms at 700° C. The thermally-insulating layer can include a plurality of microballoons to decrease the density of the thermally-insulating layer.
