As a critical advanced filtration material, Ceramic Foam Filter (CFF) stands out with its 3D interconnected porous structure, exceptional high-temperature resistance, and superior impurity-trapping capabilities. Engineered to address the strict purification demands of modern industrial production, CFF has become an indispensable component in metallurgy, casting, environmental protection, and new energy sectors. Whether you aim to enhance metal casting purity, comply with stringent emission standards, or optimize production efficiency, Ceramic Foam Filter delivers reliable, cost-effective solutions that drive operational excellence.
Key Applications of Ceramic Foam Filter
With customizable materials (alumina, silicon carbide, mullite, etc.) and pore sizes (20–100 PPI), Ceramic Foam Filter adapts to diverse harsh working conditions. Its most impactful applications include:
1. Metal Melt Purification in Casting & Metallurgy
The largest application area of CFF is metal melt filtration, especially in aluminum, steel, and copper alloy casting. Its unique porous structure effectively intercepts non-metallic inclusions (oxides, slag) as small as a few microns—mechanical interception for particles above 30μm and surface tension retention for smaller ones. For aluminum casting, a 30 PPI alumina-based CFF can reduce Fe and Si impurities by over 40%, significantly improving casting cleanliness and mechanical properties. It also reduces hydrogen content in molten metal by adsorbing gas-attached inclusions, eliminating casting defects like porosity. Widely used in automotive parts, aerospace components, and high-precision aluminum foil production, CFF ensures consistent quality for high-value-added metal products.
2. High-Temperature Flue Gas Filtration for Environmental Protection
Driven by global environmental regulations, CFF plays a vital role in industrial flue gas purification. With heat resistance exceeding 1600℃ (up to 1750℃ for silicon carbide-based products), it performs efficiently in high-temperature flue gas scenarios like steel mills and cement plants. CFF achieves over 99.5% filtration efficiency for particulate matter at 600℃+, easily meeting strict emission standards (particulate concentration ≤10 mg/m³). Its service life is 3–5 times longer than traditional filter materials, reducing replacement frequency and operational costs. It`s also applied in VOCs treatment systems, serving as a stable catalyst carrier to enhance pollutant degradation efficiency.
3. New Energy & High-Precision Industrial Filtration
In the new energy sector, CFF supports the high-purity requirements of battery manufacturing. It effectively filters metal impurities in electrolyte and electrode materials to below 0.1ppm, ensuring battery safety and extending cycle life. In solar energy production, it purifies molten silicon during photovoltaic silicon ingot casting, improving cell conversion efficiency. Additionally, its excellent chemical inertness (resistant to pH 2–12 environments) makes it ideal for chemical processing, filtering corrosive fluids and protecting downstream equipment. In nuclear power, specialized boron carbide CFFs serve as neutron absorbers, ensuring operational safety.
4. Specialized Filtration in Emerging Fields
CFF is expanding into high-value emerging applications. In aerospace, ultra-lightweight CFFs withstand 1900℃ for 300+ hours, supporting spacecraft thermal management systems. In biomedicine, it acts as a high-precision filtration device for pharmaceutical production, meeting GMP standards. It`s also used in aquarium biofiltration as a stable medium for beneficial bacteria colonization, maintaining water quality naturally.
