    摘要: Described in a joining agent for joining electrically ceramic bodies by heating the joining agent inserted at the parts to be jointed between the ceramic bodies with an electric current flowing predominantly through the joining agent at high temperature. The joining agent is superior in the wetability and reactivity with the ceramics to ensure the joint part strength. The joining agent includes, as an electric conductor, an electric conductive component made of an ion conductor consisting of fluoride, chloride, and/or oxide, which forms carrier ions by the pre-heating and has an electric conductivity higher than that of the ceramic body at the electric current supplying time. During the supplying electric current to time, the joining agent has the electric resistance increased gradually at the molten state of the joining agent by decreasing the density or the mobility of the carrier ions. After the electric heating, the joining agent is changed into a composition having a high electric resistance and hence the electric current path moves smoothly.

    摘要: The present invention provides an electric joining method of a body to be jointed including the butted portion of at least between electroconductive ceramics to be jointed or between an electroconductive ceramics and a metal to be jointed, whereby the body to be jointed is electrically jointed while the thermal stress generated at the ceramics materials to be jointed is eased. In the electric joining method according to the present invention, at least a pair of electrodes are brought to butt against the materials to be jointed holding at least one or more butted portions therebetween, with a joining agent interposed at the butted portions. Moreover, there provided are a first heating means for heating the materials to be jointed between the electrodes by Joule heat through impression of a voltage between the electrodes and, a second heating means for heating a part of said materials to be jointed and its vicinity where a large temperature gradient is formed only by the first heating means. The temperature of the butted portion is raised to a desired joining temperature while both the first and the second heating means are used together so that the thermal stress generated because of the temperature gradient at the materials to be jointed becomes smaller than the breaking stress of the materials to be jointed.
