High strength alumina composite.

Zircar Refractory Composites Inc. introduced Refractory Sheet Type RS-99, a medium-density, fiber reinforced ceramic composite material with greater than 99% alumina 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 furnace components.--Zircar Refractory Composites Inc.
