Fused Silica
Fused silica is an amorphous, high-purity SiO₂ material valued for low thermal expansion and thermal-shock resistance.
Description
Produced by melting high-purity silica and rapidly cooling to a vitreous state. It is used in investment casting shells, fused silica refractories, and components that benefit from low thermal expansion.
Applications
- Investment casting shells and refractories
- Thermal-shock-resistant components
- Insulating and precision parts in thermal equipment
Packaging
- Bagged or drum-packed on pallets with batch labeling
- Avoid contamination with metallic or ferrous particles
- Protect from moisture during storage and transport
Storage
- Store dry and covered; reseal after opening
- Keep segregated to prevent cross-contamination
- Use FIFO for multiple deliveries
