Silica

Product Benefits

Silica, in its various forms, is the primary filler and is added indirectly to the body in combination with other components and as a separate component.  Silica, in its various forms, is found in most countries.

The main properties given to the FFC body are:

  • Silica works with the fluxing oxides to fuse the body in firing
  • Control of thermal expansion
  • Increases whiteness of the body
  • Increases cast rate.

Technical Details

At Sibelco we generally consider the supply of silica and fillers to be a local solution. Please contact your local Sibelco Office for help and advice on meeting your requirements for raw sand, quartz or ground sand.
