SIC WHISKER REINFORCED SI3N4 COMPOSITE SINTERED COMPACT AND PRODUCTION THEREOF |
摘要 |
PURPOSE:To enable densification of sintered compact by ordinary sintering and improve strength and breakage toughness thereof even when the sintered compact is reinforced with a dispersed SiC whisker by limiting fiber concentration of SiC whisker in Si3N4 composite sintered compact. CONSTITUTION:The aimed Si3N4 composite sintered compact is reinforced by dispersing SiC whisker so that fiber concentration of SiC whisker in Si3N4 composite sintered compact may be 10<7>-10<9> numbers/g. The SiC whisker has preferably 0.75-4mum diameter and 70-100mum length. The Si3N4 composite sintered compact can be formed by sintering under the atmospheric pressure. |
