Abstract

PURPOSE:To obtain a high elasticity modulus characteristic with a light and high- strength diaphragm, by constituting the carbon diaphragm by the carbon porous material of the ternary net structure of cell diameter 0.5-6mm.. CONSTITUTION:The surface of carbon porous material 4 having continuous hollow holes of a uniform cell diameter in the range of cell diameter 0.5-6mm. is covered with coating material 3 such as the metallic thin film consisting of titanium, aluminium, and so on, thereby forming a diaphragm.
