Abstract
An improved process for providing a bond between carbon substrates using particles of a thermally stable solid is described. In particular, a laminate of a porous carbon substrate and a relatively non-porous carbon substrate using finely divided particles of a thermally stable solid which are in contact with and between both substrates is heated in the presence of a carbonizable gas, such as methane, in a chamber such that the gas contacts the carbon substrates and the particles so that a mutual coating of pyrolytic carbon is deposited on the exposed surfaces of all components and bonds them together. More than two carbon substrates can be bonded using the particles as interlayers between the substrates. The pyrolytic carbon coated composite products are particularly useful as electrodes.
