High strength alumina composite.Zircar Refractory refractory Material that is not deformed or damaged by high temperatures, used to make crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. Composites Inc. introduced Refractory Sheet Type RS-99, a medium-density, fiber reinforced ceramic composite material composite material or composite, any material made from at least two discrete substances, such as concrete. Many materials are produced as composites, such as the fiberglass-reinforced plastics used for automobile bodies and boat hulls, but the with greater than 99% alumina alumina (əl  `mĭnə) or aluminum oxide, Al2O3, chemical compound with m.p. about 2,000°C; and sp. gr. about 4.0. purity. It exhibits good hot strength and creep resistance and is useful up to 3,002F (1,650C). Type RS-99 resists the flow of hydrogen or other hot gasses through its thickness and is ideal for high vacuum atmospheres where silica cannot be tolerated, such as investment casting investment castingPrecision casting for forming metal shapes with minutely precise details. Casting bronze or precious metals typically involves several steps, including forming a mold around the sculptured form; detaching the mold (in two or more sections); coating its furnace components.--Zircar Refractory Composites Inc.
