PURPOSE:To provide the subject sintered compact substantially improved in thermal shock resistance, the lack of which has been problematic in conventional aluminum nitride sintered compacts, thus applicable to sites at elevated temperatures. CONSTITUTION:The objective sintered compact characterized by containing 5 to 40wt.% of silicon carbide in the form of lamellar particles 10 to 20 in aspect ratio. This sintered compact is markedly improved in thermal shock resistance, the lack of which has been a drawback of conventional aluminum nitride sintered compacts, thus paving the way to a material applicable at elevated temperatures. |
