SGS Zirconia Porous Foam Ceramic Filter for Metal Casting

Zirconia ceramic foam filter is a porous material with a high-temperature properties, its diameter from the nanometer to the micron range, porosity is from 20% to 95%, and the use of a temperature can reach up to 1600° C. Zirconia ceramic foam filter can be made by specific procedures and have peculiar bone-frame holes just like the shape of foam (called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. The three-dimensional structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting. Ceramic foam filter is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry compare to similar ones.

Features:
Easily installed
Resistant to molten aluminum
Non-wetting
Excellent hot strength
Dimensionally stable
Suitable for both horizontal and vertical placement

Application:
High porosity, heat and shock resistance, high intensity, high specific surface area and good stability, seiving, capturing slag and nidation. Besides filtering molten metal with high temperature, our products can be used as dealing with high temperature gas, catalyst substrate, solid heat exchanger, special packing and so on.
