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.
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.
