ELECTRIC CONDUCTIVE CERAMICS AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a electric conductive ceramics easy to produce and having a stable electrical conductivity at normal temperature and high safety. SOLUTION: The alumina board 1 is molded by a raw material of alumina ceramics and sintered. The sintered alumina board is laid on a charcoal powder, contacted with the charcoal powder and heat-treated at >=1400 deg.C in reducing atmosphere.
