ZIRCAR Refractory Composites, Inc.ZIRCAR Refractory Composites, Inc. (Florida, N.Y.) introduces Refractory Sheet Type RS-99, a medium-density fiber-reinforced ceramic composite material with greater than 99% Alumina purity. It exhibits excellent hot strength and creep resistance and is useful to temperatures up to 3002°F. Type RS-99 resists the flow of hydrogen or other hot gases through its thickness. It is ideal for high-vacuum reducing atmospheres and other applications where silica cannot be tolerated, such as solid oxide fuel cells, setters for P/M and MIM applications, and high-temperature investment-casting furnace components.
