Thermal Ceramics MRI FS-99V Pre-Fired Refractory Shapes
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: MRI pressed fired shapes are used in a variety of alloy melt-pour systems. The pressed manufacture process meets the tight tolerance specifications required by end users. Precise size dies and detailed product inspection provide the user with a high-quality, dimensionally accurate refractory shape.


  • Variety of available compositions in high alumina and fused silica.
  • Extreme tight tolerance capabilities
  • Low gas permeability to ferrous alloys
  • Good non-wetting characteristics
  • Excellent mechanical strength
  • Proven performance in super alloy, investment
  • Applications:

  • Standard size crucibles and liners for induction melting and investment casting
  • Tundish nozzles - meet user demands on pour stream and pour speeds
  • Gas atomized nozzles - for custom-designed atomizing powder metal systems
  • Information provided by Thermal Ceramics
