Product Overview
Amorphous fused silica powder for battery-ceramic kiln setter development, supporting low-expansion, clean-firing and thermal-cycle screening in fixture and support formulations.
Material Identity and Grade Information
Fused silica is an amorphous SiO₂ material with a different phase identity from cristobalite and natural crystalline silica. This product is for setter, support and refractory-body development around battery-ceramic firing; phase and purity must be confirmed by the current TDS/COA.
Properties / Specification
| Property | Guidance |
|---|---|
| Phase identity | Amorphous fused silica; confirm by current phase report. |
| SiO₂ / trace chemistry | Grade-specific; confirm purity and Fe/alkali limits by current TDS/COA. |
| Particle size | Grade-specific μm range; select packing and forming behavior for the setter recipe. |
| Thermal expansion | No universal value stated; measure on the formulated body under the target cycle. |
| Clean-firing | Confirm contact contamination, volatilization and part-release behavior in the actual furnace. |
| Packaging | Dry sealed packaging; confirm pack size and handling requirements. |
Values marked Grade-specific must be confirmed by the current TDS/COA. Use customer trial data for final acceptance.
Applications
Battery-ceramic kiln setters
Screen pressed or cast setter bodies for flatness retention and repeat firing under the customer’s profile.
Sacrificial supports and trays
Compare clean-firing behavior where support powder must not contaminate a ceramic surface.
Thermal-cycle fixture development
Link phase, PSD and binder burnout to crack control and service-life observations.
Grade Selection / Engineering Boundaries
Do not transfer semiconductor EMC or potting data to kiln furniture. Setter performance depends on body composition, binder, forming pressure, atmosphere, contact area and furnace ramp/hold conditions.
Production, Testing and Quality Documents
- Confirm amorphous phase, PSD, trace chemistry and moisture on the current TDS/COA.
- Run a small setter coupon through the full battery-ceramic firing cycle.
- Inspect flatness, cracking, release and contact contamination after repeated cycles.

FAQ
Why specify fused silica rather than cristobalite?
The phase identity is different. Fused silica is amorphous and should be evaluated for its own expansion, firing and contamination profile.
Can you guarantee setter life?
No. Setter life is formulation- and furnace-specific; repeated-cycle coupons are required.
