Artificial Synthetic Cordierite For Refractory Products Saggars, Kiln Furniture, Gasburners, Etc.

1. Cordierite Introduction

As an engineering material, cordierite has many applications in different fields exploiting its unique electrical, mechanical and thermal prop-erties. The synthetic aspect of cordierite is of constant interest to researchers. Elucidation ofits structure and establishing the properties ofits structure has always been considered a fas-cinating subject by researchers.

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.
