<P>PROBLEM TO BE SOLVED: To manufacture a ceramic sintered compact containing titanium diboride and boron nitride as essential ingredients by increasing productivity. <P>SOLUTION: A method for manufacturing the ceramic sintered compact comprises compacting a raw material powder which contains boron nitride powder having the maximum values of the frequency particle distribution at the area of 0.5-5 μm and at the area of 5-50 μm, and titanium diboride powder, and, thereafter, sintering the compacted raw material powder in a non-oxidizing atmosphere. In this case, preferably the raw material powder further contains sintering aids selected from an aluminum nitride powder, aluminum nitride powder and a calcium oxide powder and/or strontium oxide powder. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
