  • ZRCI Introduces 99% High Alumina Materials

    Type RS-99’s high Alumina content is ideal for high vacuum, reducing atmospheres and other applications where silica cannot be tolerated, such as in Solid Oxide Fuel Cells and setters for P/M and MIM sintering applications. Refractory Sheet Type RS-99 is available in three versions:

    • Type RS-99M is a highly plastic moldable sheet ideally suited for forming custom geometry.

    • Type RS-99W boards can be moistened with water and molded into any desired shape. After low temperature bake-out of 300°C (570°F) material is unaffected by moisture.

    • Type RS-99R boards are prefired and are unaffected by moisture. They remain rigid even if saturated with water.

      Please go to our web site www.zrci.com for more information on the Type RS-99R or any of our high temperature products. For more information please contact:

  • ZRCI Introduces New Lower Cost Alumina Ceramic Composite

    Type RS-1200

    ZIRCAR Refractory Composites, Inc., Florida, NY is proud to announce the introduction of Refractory Sheet Board Type RS-1200.

    ZIRCAR Refractory Sheet Type RS-1200 is a high strength composite designed for use as thermo-mechanical and electrical insulation in applications with temperatures as high as 1300°C(2372°F). RS-1200 is a combination of strong reinforcing fibers tightly bound in an alumina ceramic matrix. RS-1200 is completely inorganic and contains no asbestos or RCF fibers. RS-1200 exhibits greater refractoriness and homogeneity than other reinforced alumina matrix composite products and can be readily machined to tight tolerances with conventional carbide tooling.

  • ZRCI RS-100 A Fiber Reinforced Structural Alumina Composite

    ZIRCAR Refractory Composites, Inc., (ZRCI) Florida, NY is proud to announce the introduction of Refractory Sheet Type RS-100 in new larger size boards. It is now available in 48” x 48” as a standard size.

    Refractory Sheet Type RS-100 is a fiber reinforced structural Alumina composite with useful properties in thermal, structural and electrical insulation applications, as well as in the transport of molten non-ferrous metals to 1260OC(2300OF). Type RS-100 has compressive and flexural strengths in the range of high temperature reinforced plastics, such as G-10 laminates, but retains its strength and utility to levels far exceeding the maximum use temperatures of plastics. The mechanical properties of RS-100 exceed those of all calcium-silicate materials, as well as Transite and other asbestos cement materials, over all temperature ranges. Therefore, Type RS-100 not only makes an excellent replacement for rigid asbestos-containing products, but it can also be employed at much higher temperatures. Type RS-100 is 100% inorganic, non-flammable and contains no asbestos. Its high Alumina content makes it highly resistant to many environments, including molten non-ferrous metals, and it undergoes no out-gassing upon heating. It is not brittle and has high impact properties. RS-100 may be cut and machined with standard tooling.

  • Refractory Sheet Type RSLE-57
    ZIRCAR Refractory Sheet Type RSLE-57 is a low expansion high strength reinforced silica matrix composite. This remarkable material was designed for use as a high strength insulator in induction hot press applications....

  • RSLE-57’s very low thermal expansion coefficient and high hot strength combine to give it thermal shock resistance not found in other structural ceramic matrix composite materials. 

    RSLE-57’s exhibits a very low coefficient of expansion 0.3 x 10-6 °C  which provides remarkable resistance to the thermal shock up to 1200°C (2192°F)* in an oxidizing atmosphere and permits its use with rapid variation in temperature in that zone. Beyond 1200°C (2192°F) it transforms into a crystalline structure and becomes brittle. If the exceeded temperature is only localized, the material still  retains its original high strength properties.

    RSLE-57 also exhibits exceptional non-wetting properties when used in contact with molten aluminum making it useful in numerous molten aluminum contact applications.

    RSLE-57 is 100% organic free and contains no refractory ceramic fiber. It is readily machined to precision tolerances with conventional tooling.

    ZIRCAR Refractory Composites, Inc. (ZRCI) has developed a new material for the production of diamond segments that is far superior to all other high temperature, high pressure insulation. It has proven to be the best insulation material for Dr. Fritsch as well as other diamond segment sintering machines.

    ZIRCAR Refractory Sheet Type RSLE-57 is an integral part of the production of hot pressed diamond segments. It is used as a separator to electrically and thermally insulate a metal frame from a graphite pack. It will see in excess of 1000°C (1832°F) with several thousand pounds per square inch compression without any surface deformation.

    RSLE-57 is a low expansion, high strength reinforced silica matrix composite. Designed for use as a high strength insulator in induction hot press applications, it is ideal for any application, which requires a material with superior hot strength at temperatures as high as 1200°C (2192°F). RSLE-57’s very low thermal expansion coefficient and high density combine to give it thermal shock resistance not found in other structural ceramic composite materials. These properties give it much greater life in most hot pressing and induction heating applications. This thermal stability also helps to increase the life of the graphite.

  • Refractory Sheet Type RS-100
    Refractory Sheet Type RS-100 is a ceramic fiber reinforced structural alumina composite material with useful properties in thermal, structural and electrical insulation applications....

  • ZIRCAR Refractory Sheet Type RS-100 is a ceramic fiber reinforced structural alumina composite material with useful properties to 1260°C (2300°F). It has exceptional flexural and compressive strengths in the range of high temperature reinforced plastics such as G-7 and G-10 laminates and retains strength and utility to levels far exceeding maximum use temperatures of plastics. Mechanical properties of Type RS-100 sheet far exceed those of asbestos-cement materials and it is an excellent replacement for these rigid asbestos-containing products. Type RS-100 can also be employed at much higher temperatures than these types of products.

    Type RS-100 is 100% inorganic, non-flammable and contains no asbestos. Its high Al2O3 content makes it highly resistant to many environments, including molten aluminum. It undergoes little or no outgassing on heating. It is not brittle and has high impact properties. Type RS-100 may be cut and machined with standard tooling. Type 100 sheet is used both as a full-size panel and as a source for precision-cut fabricated components.

    Refractory Sheet Material is available in Cylinder form asRefractory Sheet Type RS-101 Cylinders.

  • Silica Blanket Type SB-2000
    ZIRCAR Silica Blanket Type SB-2000 is a high temperature insulation blanket made of mechanically interlocked continuous filament amorphous silica fibers....

  • ZRCI Silica Blankets Type SB-2000 is a high temperature insulating blanket produced from mechanically interlocked amorphous silica fibers. The high purity, shot free amorphous silica fibers are needled into a strong, durable product with useful properties to temperatures of 1100°C (2012°F). Type SB-2000 Blankets are non-hazardous as they contain no asbestos or Refractory Ceramic Fiber (RCF). The non-respirable fibers are between 6 to 9 microns in diameter and between 2"- 4" in length and pose no health risk associated with Refractory Ceramic Fibers. Type SB-2000's physical strength, resistance to hot air erosion and vibrational degradation makes it superior to refractory ceramic fiber insulation in many applications. Type SB-2000 blankets exhibits excellent thermal shock resistance, low thermal conductivity and heat storage. It is highly resistant to attack by most chemicals and harsh atmospheres. Exceptions include strong bases and hydrofluoric acid. Type SB-2000 is easily cut with a knife, scissors or die punch and can be installed without gloves. It is soft to the touch and not itchy or irritating.
