Technical calcium silicates

MONALITE® materials are asbestos fibre free technical ceramics made from calcium silicate in a density range from 850 to 1000 kg/m3.  MONALITE® is the standard product for use in aluminum casting and the foundry industry and is also used in the furnace industry and other process
industries. MONALITE®–M1T is the standard product for contact with molten metals up to 850 °C with low shrinkage. MONALITE®–M1AT is an improved version with higher strength and dimensional stability up to 1000 °C.

Properties & advantages

  • Low thermal conductivity
  • Low thermal capacity
  • Extremely high thermal shock resistance and fracture toughness
  • Non wetted by liquid non-ferrous metals, non reactive to lubricants such as boron nitride or graphite
  • Asbestos free
  • Dimensionally stable and wear resistant
  • Excellent machinability to close tolerances

Application areas

HEAVY INDUSTRY                                                                  

The non wetting properties of MONALITE® mean that these products are ideally suited for use in non-ferrous casting applications.

  • Billet and ingot casting as transition plates, floats, spouts
  • Head boxes for continuous casters
  • Tips for continuous sheet casters
  • Sprue bushes, tubes, nozzles and feeder box liner in low pressure die casting
  • Hotface linings for dosing/holding furnaces
  • Launders and dams
  • Load bearing housings
  • Structural insulation where high thermal and/or mechanical load is required

OIL AND GAS INDUSTRY                                                      

  • Collars, gaskets and pipe support rings
  • Spacers and bushes
  • Thermal separation for high loads
