Product Description
Zirconia Foam Ceramic Filter
A zirconia-based foam ceramic filter is a high-performance porous material manufactured by coating zirconium oxide (ZrO) ceramic slurry onto a three-dimensional reticulated organic foam carrier, followed by drying and high-temperature sintering6. This structure provides exceptional thermal stability (withstand temperatures up to 1700C) and chemical resistance, making it ideal for molten metal filtration in casting processes25.
Key features include:
High porosity and uniform pore distributionto effectively capture inclusions (slag, oxides) in steel, iron, copper, and aluminum alloys28.
Enhanced mechanical strengthcompared to traditional alumina or silicon carbide filters, improving durability under extreme conditions56.
Reduced casting defectssuch as sand holes and gas porosity, significantly lowering scrap rates in industrial production8.
Widely used in foundries for automotive, aerospace, and machinery components, it ensures cleaner molten metal flow and improved product quality.
