    摘要: An oxidation resistant carbon-carbon composite (31) including a plurality of graphite fibers (13) within a carbonized (graphitized) matrix (14). A first material including boron (16) and a second material including silicon (18) are applied thereto. Heating the composite in the course of service use to a temperature at which the composite cracks enables the boron and silicon to combine to provide a borosilicate sealant of sufficiently low viscosity for sealing cracks in the composite.

    摘要: The present invention is directed to an improved cutting tool blank formed by hot pressing a mixture of finely divided high-purity alumina and from about 0.05% to 0.35% of magnesia. Up to 0.10% nickel oxide may be present. The hot pressing temperatures are effected at a temperature in the range of about 1300.degree.C to 1525.degree.C so that the crystal size of the alumina in the tool blank has an average size range from 1 to 2 microns and the pressed blank has a final product density in excess of 3.97 grams per cubic centimeter. The preferred density of the blank is in excess of 3.98 grams per cubic centimeter. The hot pressing is conducted under vacuum conditions.
