Abstract
General aspects are considered for using foam-ceramic filters in casting. Examples are given of these filters used under laboratory and industrial conditions for filtering aluminum, magnesium, and ferrous alloys. It is shown that the filter material affects the microstructure and properties of the filtered alloy. Future lines for such research are formulated.
