Abstract:
A less breakable highly heat-resistant sintered SiC fiber-bonded material comprising inorganic fibers which are composed mainly of a sintered SiC crystal, contain at least one kind of metal atoms selected from the group consisting of metal atoms of the 2A, 3A and 3B groups of the periodic table in a structure in which metal atoms are bonded to Si atoms directly or other elements and are bonded nearly in the closest packing state and 1 to 50 nm boundary layers composed mainly of carbon which are present at the interface of fibers, the less breakable highly heat-resistant sintered SiC fiber-bonded material having a density of at least 2.7 g/cm.sup.3 and an elastic modulus of at least 200 GPa.
