| Typical Technical Parameters |
| |
| Kiln Furniture (Cordierite Based) |
| |
| Shapes |
 |
| Batts/Tiles, Trays/Saggers, Supports/Setters |
|
|
| |
| Properties |
|
1) High Thermal Shock Resistance.
(Due to low co-efficient to thermal expansion.) |
| 2) Suitable for faster firing cycle. |
| 3) Low bulk density leading to minimum storage of heat. |
| 4) Higher temperature application upto 1350 |
| 5) Excellent resistance to sagging and distortion. |
| 6) Does not oxidise, spitout or discolour the product. |
