  • Patent number: 7459104
    Abstract: A lead free, thick film heating element. Known thick film heating elements contain environmentally hazardous material such as lead. This is particularly problematic when manufacturing thick film heating elements, as lead is often used in thick film formulations to allow the glass-based thick film to be processed at low firing temperatures. Using composite sol gel technology, the present invention provides a method to produce a lightweight mica-based thick film heating element based on thick film materials that are free from lead or cadmium. This mica-based element is lightweight, has the performance advantages of a thick film heating element, and may be processed at a low temperature using thick film materials.
