Refractory Materials

From the fireclay brick to high-tech refractory castables – an overview of the key refractory materials in industrial furnace construction.

Refractory Bricks

Fireclay bricks

up to 1,400 °C

The classic in refractory construction. Versatile in use for standard applications in chamber furnaces, tunnel kilns and combustion chambers.

  • Good thermal shock resistance
  • Cost-effective
  • Easy to work with

High-alumina bricks (Al₂O₃)

up to 1,800 °C

For the highest temperatures and chemically loaded areas. The higher the Al₂O₃ content, the more resistant the brick.

  • High compressive strength
  • Chemically resistant
  • Long service life

Corundum & chrome corundum bricks

up to 1,900 °C

Premium materials for extreme stress: slag contact, aggressive atmospheres and the highest temperatures.

  • Extreme resistance
  • Slag-resistant
  • For special applications

SiC bricks (silicon carbide)

up to 1,600 °C

Excellent for wear protection and areas with high abrasion loads. Very good thermal conductivity.

  • High abrasion resistance
  • Good thermal conductivity
  • Alkali-resistant

Refractory Castables & Mixes

Refractory castable (conventional)

up to 1,600 °C

Cast or gunned refractory castables for complex geometries and large-area linings.

  • Flexible in shape
  • Quick to install
  • Good adhesion

Low-cement castable (LCC)

up to 1,700 °C

High-strength refractory castables with reduced cement content for improved high-temperature properties.

  • High strength
  • Low porosity
  • Long service life

Ramming mixes

up to 1,800 °C

Dry-rammed mixes for furnace hearths, launders and crucibles. Compacted by ramming or vibration.

  • Joint-free installation
  • High density
  • Suitable for melt contact

Gunning mixes

up to 1,700 °C

Machine-applied refractory mixes for rapid repairs and areas that are difficult to access.

  • Rapid repair
  • Good adhesion
  • Reduced downtime

Mortars & Adhesives

Refractory mortar

up to 1,600 °C

For laying refractory bricks. Thin-bed mortar for narrow joints, thick-bed mortar for levelling.

  • Matched to temperature
  • Thin-bed or thick-bed
  • Standard-compliant

Refractory adhesive

up to 1,400 °C

For bonding ceramic fibre modules, boards and shaped parts to steel or brick substrates.

  • Immediate adhesion
  • For fibre materials
  • Simple application
