Silicon Carbide Setters
Used to support ware in firings which are above 1250°C and where improved resistance to bending is required.
Also used in low temperature applications where weight and energy saving is necessary.
Cordierite setters are also available.
- Stronger and more durable than cordierite setters
- Can be made thinner and lighter than cordierite setters
General Overview
IPS Ceramics’ Silicon Carbide Setters are used to hold and support ware during the firing process. They are much stronger than cordierite setters and can be made thinner and lighter, reducing refractory-to-ware ratios. They are used for firings above 1250°C (2280°F) where an improved resistance to hot-bending is needed, or in lower temperature applications where weight and energy saving is necessary.
The unusual shape of these setters allows stacks of them to be closely packed, maximising kiln-fill. They are available in a wide range of sizes depending on your exact requirements.
