Resistive paste, electric heating resistance and preparation process using this paste.

摘要

Disclosed are an exothermic conducting paste mainly comprising a synthetic resin and a heat stable metal oxide which is positive in temperature coefficient of electric resistance and has an electric specific resistance of not more than 5x10<3> mu OMEGA cm at ordinary temperature, and an electric resistance heating unit wherein a desirably shaped solid or solid surface is coated or impregnated with said paste. This heating unit has an uniform temperature distribution, is arbitrarily adjustable to a desired temperature below 350 DEG C, and further can be formed in various shapes.
