| 摘要 |
<p>A refractory composite article includes a plurality of continuous, polycrystalline stoichiometric silicon carbide reinforcing fibers in an inhibited carbon matrix; the carbon matrix is an organic resin containing an inhibitor compound that has been subjected to carbonization and thereafter to densification by chemical vapor infiltration of at least carbon to form a silicon carbide fiber reinforced carbon composite; and the silicon carbide fiber reinforced carbon composite is coated with a SiC pack cementation coating to form the refractory composite. The pack cementation coating is prepared by providing a pack mixture composition; coating the composite with a release agent; surrounding the release agent-coated composite with the pack mixture composition; and firing the composite to form a protective SiC pack cementation coating on the composite.</p> |
