Cryston® Cu Max Hot Face Bricks

Hot Face Bricks

The Cryston® Cu Max material’s enhanced oxidation resistance ensures superior furnace life versus traditional nitride and clay bonded silicon carbide products.

This increases the chemical resistance to copper oxide and is not wetted by molten copper.

These properties, coupled with its high temperature mechanical strength, and improved impact and abrasion resistance make Cryston® Cu Max an excellent choice for hot face brickwork.

Saint-Gobain Performance Ceramics & Refractories’ refractory design concept and use of specialized cement ensures minimal slag and refractory inclusion, yielding a potentially cleaner metal.

Features and Benefits

  • Patented composition designed for oxidation resistance
  • Self-protecting silicon-oxynitride bond phase
  • Thermal shock resistance
  • High density and deep, uniform nitridation
  • High quality silicon carbide grain
  • Years of reliable service life
  • Assurance of predictable performance in critical equipment
  • Low total cost of ownership
  • Reduced maintenance costs


Does the use of Cryston® Cu Max bricks improve furnace lifetime?

Yes. The average customer gains between 30% and 50% more refractory service life, with some installations, even doubling this.

What is the recommended thickness for the hot face brick?

Standard 115 mm (4.5”) and 150 mm (6”) inch hot face bricks are available. Conversion to thicker linings can be facilitated through the use of DryVibe safety lining.

What mortar is typically recommended for use with hot face bricks?

Different mortars are more suitable for each area of the furnace. Saint-Gobain Performance Ceramics & Refractories’ experienced engineering teams are on hand to provide advice and support around this particular application.
