    摘要： A method of producing alumina-silica ceramic with mullite whisker structure has been produced as armor materials for protecting high velocity projectile. The mixing composition of starting powders consists of alumina, quartz, kaoline, feldspar and talc, and the green compacts were sintered at the temperature range from 1200 to 1450null C. for 0.5 to 3 hours. Mullite whisker structure in the ceramic was fabricated and grown in the period of liquid phase sintering. The whisker phase of mullite is homogeneously distributed in the ceramic.

    摘要： A ceramics composite material containing crystallized glass as the matrix and fibers or whiskers of ceramics as a reinforcement material, is obtained by melting original glass to form crystallized glass, compounding the same with fibers or whiskers of oxide ceramics and thereafter crystallizing the original glass. This ceramics composite material does not form any voids and can easily contain at least 50 volume percent of the reinforcement material, whereby a good mechanical strength and fracture toughness are achieved. In the compounding step, the content of the reinforcement can be further increased by forcing out any excess part of the original glass from the reinforcement material by applying pressure to a substance obtained by mixing the original glass with the reinforcement. Further, the ceramics composite material can be efficiently formed into a desired configuration by heating because the original glass flows viscously.

    摘要： Ceramic insulation has a mat of intersecting, discrete ceramic fibers bonded with a sol-gel glass binder. A fabric-reinforced glass coating is bonded to at least one surface of the mat. The insulation is prepared by forming a slurry of ceramic fibers, molding the slurry to form a soft felt mat, drying the mat, and incrementally introducing the binder into the mat with a multiple-impregnation technique, which controls shrinkage of the ceramic fiber mat. The fabric-reinforced glass coating is formed by applying a glass fiber cloth to a surface of the ceramic fiber mat and coating the same with a powdered glass. The powdered glass is melted and cooled.The process provides a layering technique that permits formation of a continuous fibrous structure having layers that impart distinct characteristics at desired regions within the structure. By using different ceramic fibers and fibers of differing physical dimension, or by including additives with the slurries, tailoring of the physical characteristics of the insulation is achieved.Improved properties are obtained by stitching the fiber cloth to the mat, curing the glass binder in a nitrogen atmosphere to replace oxygen in the glass with nitrogen, using a barrier coated cloth within the glass overcoat, or any combination thereof.

    摘要： A process for making a porous ceramic composite with a bimodal pore size distribution includes the steps of mixing an organosilicon precursor, an alcohol, water, a catalyst, granules, particles, whiskers or powders of a fumed silica and granules, particles, whiskers or powders of a ceramic material and a combustible material having a diameter in a range of 500 angstroms to 500 microns to form a mixture, pouring the mixture into a mold, allowing the mixture to gel form a ceramic composite and drying the ceramic composite. The process also includes the step of heating the ceramic composite in either air or oxygen to burn away the combustible material. The organosilicon precursor is selected from a group consisting of tetramethoxysilane, tetraethoxysilane, tetrapropoxysilane and tetrabutoxysilane. The alcohol is selected from the group consisting of methanol, ethanol, propanol and butanol.
