Abstract: This invention relates to integrated heaters for use in a wide range of consumer and industrial applications. The integrated heater capable of high temperature operation includes a substrate that is coated with a suitable electrically insulating coating, a resistive heating element which may be a foil, ribbon or wire, placed on top of the electrically insulating coating, and a high temperature insulation material which is used to affix the heating element up against the coated substrate by sandwiching the heating element between the coated substrate and the insulating material and keep the heating element in close contact with the coated substrate. The insulating layer is able to provide both electrical insulation and efficient thermal transfer. This resulting integrated heating element is able to meet the regulatory electrical insulation requirements and is capable of operation in excess of 600° C.

Abstract: A sol gel formulation and process for making thick coatings. In accordance with the teachings of this invention, sol gel coating layers of up to 300 microns in thickness can be provided in a single deposition.

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.
