PURPOSE:To permit to use the member under high-temperature and high pressure by a method wherein ceramic, separating out onto the surface of ceramics couplings at both ends of a base body, is burnt in the manufacture of the ceramics- made connecting member. CONSTITUTION:A corrugated base surface 2, provided with the profile of a bellows, is formed on the outer peripheral surface of substantially tubular shape base body 1, which is made of graphite, and annular disc-shape ceramics couplings 3 made of silicon nitride are attached to the base body 1. The base body 1 is burnt out in an electric furnace after separating out the silicon nitride onto the surfaces of the base surface 2 and the ceramics couplings 3. According to this method, the bellows made of silicon nitride is obtained and the coupling may be used under high-temperature circumstance in which high-temperature fluid flows. |
