METHOD FOR PRODUCING FOAMED ALUMINUM USING CARBONATES

A method for producing an aluminum foam product wherein reactive gas producing particles are introduced into an aluminum alloy melt under controlled conditions and subjected to agitation to induce the production of foam-stabilizing by-products (20), and, under certain conditions, the production of g...

Beschreibung
Zusammenfassung:	A method for producing an aluminum foam product wherein reactive gas producing particles are introduced into an aluminum alloy melt under controlled conditions and subjected to agitation to induce the production of foam-stabilizing by-products (20), and, under certain conditions, the production of gases (15) used to produce the molten metal foam itself. Foam products produced through this method have intrinsically formed metal oxides (20) and other solid particles dispersed therein and are devoid of the large extrinsically added stabilizing ceramic additions traditionally used in the production of aluminum foams. The invention claims a rapid, single step method for producing an inoculated, foamable melt using low cost precursor materials.
