Abstract

PURPOSE:To obtain an electrolyte with excellent supporting capacity for the electrolyte and large mechanical strength, by adding an alkali fused carbonate into a finely pulverized refractory substance, mixing, humidity-controlling, granulating into pellets, then by compression-molding, heating and sintering under the reduced pressure. CONSTITUTION:Alkali fused carbonate such as lithium carbonate, potassium carbonate or the like is added into a finely pulverized refractory substance such as lithium aluminate, alumina or zirconia or the like to make a mixture, which is mixed using a grinding machine, then added with water and all is mixed. This humidity-controlled powder is put into a metallic mold, then compressed, and the compressed molded body is pulled down to size in the dimension of 20-50 mesh. This sized powder is put into a metallic mold, compressed to form a molded body, which is then dried using a thermostat. Next, this molded body is introduced into a chamber of an electric furnace and an exhaust pump is connected to an exhaust pipe to the chamber; the inside of the chamber is exhausted, on the other hand, the electric furnace is heated at the rate of 200 deg.C/hr and the molded body is heat-treated at 500-700 deg.C.
