Alumina ceramic foam filter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and has many advantages of high porosity, high mechanical strength, stable chemical property, strong corrosion-resistant,Strong Adsorption, high adsorption rate, excellent filtering functions and thermal shock resistance.Alumina ceramic foam filter is equipped with a gasket on the edges; the gasket assures the proper and tight position of the filter within the filter box. There are different types of gasket available, e.g. ceramic fiber gasket etc., also can provide alumina ceramic foam filter without gasket.
