PURPOSE:To provide a highly reliable SiC-based composite ceramic having SiC as matrix, high in mechanical strength, furnished with adequate reinforcing effect by fibers, etc. CONSTITUTION:The composite ceramic with SiC as matrix, compounded with at least one kind of reinforcing material selected from long fibers, short fibers and whiskers. The matrix is made from a starting material containing >=80wt.% of alpha-SiC, and the average aspect ratio (major radius/minor radius) of the SiC crystal grain constituting the matrix is <=3. |
