    • A castable refractory mix composition is disclosed which when fired at a temperature of about 2300.degree. F. will yield a cast refractory article having improved thermal shock resistance and when fired at a higher temperature of about 2750.degree. F. will yield a cast refractory article having improved abrasion resistance. The castable refractory mix composition comprises from about 10 to 15% by weight of an aqueous slip of fine ground fused silica particles, from 25% to 32% by weight of fine alumina particles, from about 55 to 70% by weight of relatively large particle size silican carbide refractory particles, from about 0.015 to 0.04% by weight of a water-soluble wetting agent, and from 0 to about 5% by weight added water.

    • A method of producing a cast fused silica product includes grinding fused silica particles to have a first particle size and to form an aqueous slurry. A fused silica aggregate is provided having a second particle size greater than the first particle size. A first amount of the aqueous slurry is dried to form dried fused silica particles and the dry fused silica particles are ground to have a third particle size intermediate to the first and second particles sizes. A second amount of the aqueous slurry, the fused silica aggregate and the ground fused silica particles are admixed to form a casting mix.
    • 制造熔融二氧化硅产品的方法包括研磨熔融二氧化硅颗粒以具有第一粒径并形成含水浆料。 提供具有大于第一粒径的第二粒径的熔融二氧化硅聚集体。 将第一量的含水浆料干燥以形成干燥的熔融二氧化硅颗粒,并将干燥的熔融二氧化硅颗粒研磨成具有中间至第一和第二颗粒尺寸的第三颗粒尺寸。 混合第二量的含水浆料,熔融二氧化硅聚集体和磨碎的二氧化硅熔融石英颗粒以形成浇铸混合物。
