Cryston Max Muffle Bricks

Oxy-nitride bonded SiC

Cryston® Max muffle bricks offer remarkable performance in ZnO furnaces. This patented oxy-nitride-bonded SiC material delivers high oxidation resistance to assure consistent thermal conductivity throughout the lifetime of the product. What results is a more predictable improving fuel savings.

  • Outstanding thermal conductivity at high operating temperatures,
  • Consistent, long-term performance: no drop in heat flux as seen in competitive products,
  • Engineered shape.

Our brick shapes are optimized to promote greater heat transfer, tongue and groove construction

  • Melt more zinc with less energy consumed,
  • Experience longer arch life and more sustained heating performance,
  • Save in maintenance and installation costs.
