A method comprising the steps of: coating at least that part of the surface of a porous ceramic to which a new function is to be imparted with a precursor which can be converted into a ceramic coating having such a function upon heating, coating the entire surface of the porous ceramic with another precursor which can be converted into a gas-impermeable coating upon heating, forming a gas-impermeable coating by heating, subjecting the porous sinter to hot isotropic pressing, and removing the gas-impermeable coating. The purpose ceramic sinter can be produced by this method efficiently in a shortened process. |
