METHOD OF MANUFACTURING HIGH THERMAL CONDUCTIVE CERAMIC SINTERED COMPACT AND HIGH THERMAL CONDUCTIVE CERAMIC SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To provide a low cost ceramic sintered compact having high thermal conductivity as a electric insulating material and a method of manufacturing the same.;SOLUTION: A green sheet made of slurry obtained by mixing aluminum nitride powder, a sintering aid, a plasticizer and a solvent to magnesium oxid powder is prepared. A formed body is made of the green sheet and is sintered under an inert atmosphere, The manufactured high thermal conductive ceramic sintered compact 3 is configured by dispersing magnesium oxide particles 1 in a matrix phase 2 consisting essentially of the aluminum nitride sintered compact 4.;COPYRIGHT: (C)2007,JPO&INPIT
