Ceramic Foam Filter High Strength Heat Resistant Honeycomb Porous Zirconia Ceramic Foam Filter
Ceramic Foam Material
Ceramic foam filter, depending on the materials: alumina foam ceramic filters, silicon carbide ceramic foam filter, zirconia ceramic foam filter, and magnesium oxide foam ceramic filter.
1. Silicon Carbide Ceramic Foam Filter:
Working Temperature is 1560 Degree Centigrade. In the bronze casting process, the use of silicon carbide ceramic foam filter material is of SiC.
2. Zirconia Ceramic Foam Filter:
Working Temperature is 1700 Degree Centigrade. Steel castings uses zirconia ceramic foam filters. Zirconia ceramic foam filters material of ZrO2 zirconia. Zirconia heat-resistant temperature of the filter is higher than about 1760 ° C, with very high strength and excellent high-temperature impact.
3. Alumina Ceramic Foam Filter:
Working Temperature is 1200 Degree Centigrade. Alumina ceramic foam filter products effectively remove solid-state mixed with the molten metal, so aluminum alloy can be successfully forged, aluminum foil manufacturing, extrusion processing technology, perfect aluminum products. 10ppi coarse porosity 70ppi of fine porosity range of options.
