In common and high temperature, besides high porosity, heat and shock resistance, high intensity ,high specific surface area and good stability, sieving, capturing slag and nidation are still the characters of foam ceramic filters, all that could filter very small impurity, even micron. Even three dimensional structures could change turbulent current liquor into stable flow. After venting gas. We could mold gently, so as to improve the castings quality. Besides filtering molten metal with high temperature, our products could be used as dealing with high temperature gas, catalyst substrate, solid heat exchanger, special packing and so on.
