Thermal Ceramics Cerox 700 Shapes
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: Cerox fired refractory shapes are thixotropically cast using a dispersion agent, which allows the Cerox mix to flow when vibrated without requiring a high water content. These manufacturing techniques, combined with precisely controlled firing and 100% product inspection, produce high-quality components suited to the most arduous of high-temperature environments.

Features:

  • Variety of available compositions using high-alumina, alumina-silica, zirconia, and silicon carbide
  • Excellent chemical attack resistance
  • Excellent thermal shock resistance
  • Low gas permeability
  • Hundreds of standard molds in stock
  • Tight tolerance capability
  • Applications:

    Process Industries (chemical & mineral processing)

  • combustion chambers
  • burner blocks
  • pipes
  • gas reactor components
  • wear plates
  • crucibles
