Abstract
PURPOSE:To obtain the titled electrode material having excellent heat resistance, corrosion resistance, spark consumption resistance and thermal conductivity, by sintering mixed powder of a carbide and/or a nitride of a specific element and SiC and/or C. CONSTITUTION:50-98wt.% at least one carbide (e.g. Tic) and/or nitride (e.g. ZrN) which has <=1.0mum average particle diameter and >=5m<2>/g specific surface area and has an element selected from group IVa or group Va of the periodic table is blended with 50-2wt.% SiC and/or C which has <=1.0mum average particle diameter and >=5m<2>/g specific surface area and, if necessary, a molding auxiliary such as polyethylene glycol, molded into a desired shape and sintered in a non-oxidizing atmosphere at 2,000-2,400 deg.C for >=0.5hr to given an electrode material for ignition plug which has >=95% theoretical density, <=5% porosity, <=20mg/1cm<3> weight increase by leaving to stand at 900 deg.C in atmosphere, 1X10<-2>-1X10<-3>OMEGAcm resistivity at room temperature - 1,200 deg.C, >=2,500 deg.C heat resistance and <=8X10<-6>/ deg.C coefficient of thermal expansion at 0-1,000 deg.C.
