  • Resistive paste for the formation of electrically heat-generating thick film
    Patent number: 6406646
    Abstract: A resistive paste composition comprising 5 to 75% by weight of ruthenium(Ru) metal or ruthemium oxide particles having a specific surface area of 5 to 30 m2/g, 5 to 75% by weight of silver(Ag) metal or its compound particles having an average particle size of 0.1 to 3 &mgr;m and a maximum particle size of 8 &mgr;m or less, 5 to 40% by weight of a glass frit having a softening point of 400 to 550° C. and 5 to 45% by weight of an organic binder can be coated by a conventional screen-printing or dipping method on a substrate and then calcined at a low temperature of about 500 to 600° C. to form an electrically heat-generating thick film layer having good stability, uniformity and heat-up characteristics.
