摘要： PROBLEM TO BE SOLVED: To provide a method for sintering a ceramic by which a ceramic sintered compact having a dense structure is efficiently obtained. SOLUTION: The ceramic is sintered using SiC plates as a heating assistant in the sintering of a molding composed of inorganic ceramic powder under a microwave ranging from 300 MHz to 30 GHz frequency. The SiC plate has 10 2 -10 8 cmΩ electric resistance and the sintering is performed by arranging the SiC plates so as to sandwich a sample vertically or to surround the sample. As a result, the method of forming the dense ceramic sintered compact becomes useful for the manufacture of the sintered compact of zinc oxide, barium titanate or the like. COPYRIGHT: (C)2004,JPO
