の発熱体の製造はコストが高く々る。Electric resistance heating elements are widely used as heat sources for household and industrial purposes, and metal and non-metal types have been widely used. Although it is an excellent heating element compared to metal resistors such as dichromatic five-wires, it is easily oxidized, and when it is oxidized, it becomes brittle and easily breaks. Moreover, when local heating occurs, the resistance of that part increases, so the heat generation becomes even more localized and the wire breaks. On the other hand, non-metallic heating elements such as carbon and graphite have high decomposition temperatures, are chemically stable, have higher resistance values than metal resistors, and have advantages such as a small temperature coefficient, but they are brittle and
Also, depending on the melting point of the inorganic substance, the temperature may be too high (10
(00°C or higher), it may deteriorate or deform. Therefore, as heating elements that can withstand use at high temperatures, materials of the type sintered at high temperatures, such as molybdenum silicide and silicon carbide, are used. However, manufacturing such a sintered heating element is expensive.

効果を発揮しうろことが分った。The mold cost of the structure of the present invention lies in the use of a chlorine curing agent. Such curing agents bond particles of inorganic heat-resistant conductors and semiconductors at low temperatures, and further bond these particles by melting at slightly higher temperatures. In addition, the curing agent also acts as an electrical resistor and integrates with the solid conductor particles to provide a homogeneous resistor. Further, by using ceramic particles, the mechanical properties can be improved so that the product can be used even after being heated to 2000° C. and cooled with water. It has been found that the chlorine curing agent can be sufficiently effective if used in an amount of about 3w1% based on the total weight of the heating element material.
