Zirconia Based Ceramic Foam Filters
Our zirconia ceramic foam filters are engineered for demanding steel and alloy-casting applications. Their highly refractory structure remains stable when exposed to extreme pouring temperatures and aggressive molten metals.
The uniform, tortuous pore network captures oxides and other non-metallic inclusions while promoting controlled, laminar metal flow. This improves casting cleanliness, consistency and overall yield.
Key advantages
- Exceptional high-temperature stability
- High resistance to molten-steel attack
- Superior mechanical strength
- Efficient inclusion removal
Key Benefits
- Exceptional high-temperature stability
- High resistance to molten-steel attack
- Superior mechanical strength
- Efficient removal of non-metallic inclusions
Material Characteristics
Zirconia-based ceramic foam filters provide excellent refractoriness and thermal-shock resistance, ensuring reliable filtration under severe operating conditions.
