5. Cordierite Applications

Cordierite is widely used in various fields of ceramics. Its traditional applications are as fol-lows:

• Refractory products saggars, kiln furniture(widely popular in whiteware industries), gasburners, etc.

• Electro-ceramics resistors, fusibles, flame guards, etc.

• Tablewares Flameproof application developments in fast firing techniques which allowwide temperature variations during the cooling cycle have renewed interest in this type of body.

• Cordierite is common as a refractory filler. Refractory fillers are frequently blended with powdered solder glass to increase the strength.

A very recent application for cordierite is inmaking thick films.
