Abstract
A composition for application to a substrate to form a an electrically conductive coating thereon. The composition includes a sol-gel solution filled with a conductive powder. The coating may be conductive or resistive depending on the application. A process is provided for applying such a coating by mixing a sol-gel solution with up to about 90% by weight of the solution of a conductive powder selected from the group consisting of ceramics, inter-ceramics, semi-conductors and metals so as to provide a uniform stable dispersion. The stable dispersion is applied to a substrate and the coated substrate is fired at a temperature sufficient to remove organic constituents and to produce at least a partially conductive film on the substrate. A heating device is also provided which is a product of the above process.
