CIDOMLITE (Light Weight Filling Material)


CIDOMLITE is the geological name given to a group of hydrated laminar minerals which are aluminium iron magnesium silicates resembling mica in appearance. Minute layers of water are trapped between the plates, and when the particles are subjected to heat they have the unusual property of exfoliating, or expanding, due to the inter-laminar generation of steam.


  • Low density
  • Low thermal conductivity
  • High temperature resistance
  • High absorbency
  • High specific surface area


  • Thermal Insulation
  • Roof Surki
  • Fire Protection
  • Sound Deadening Medium


  • 7.0 to 8.0

Loose Bulk Density

The loose bulk density of CIDOMLITE is normally in the range of 100-200 Kg/m3 and is influenced by the particle size and method of processing.


  • CIDOMLITE is incombustible and can be used up to 1,100oC.

Sintering Temperature

  • About 1,260oC (2,300oF)

Melting Point

  • About 1,315oC (2,400oF)

Specific Heat

  • 0.2


CIDOMLITE is insoluble in water and organic solvents.

Absorption Capacity

CIDOMLITE will readily hold liquids within the inter-laminar voids of particles. It will also hold a certain amount between the individual particles. Water retained as a percentage of the air dry weight will be approximately 240%

Thermal Conductivity

CIDOMLITE has low thermal conductivity and high thermal insulation properties. The thermal conductivity at normal atmospheric temperatures:
K=0.43 – 0.45 Btu in/ft2hoF
K=0.062 – 0.065 W/moC
