FIELD: metallurgy.
SUBSTANCE: mould cavity for the articles of aluminium foam is filled with water-soluble granules of a mixture of baking soda and gelatin in the ratio: 95-99.5% of sodium, 0.5-5% of gelatin, and is heated to the melting temperature. Aluminium melt is poured into a mould, while the melt fills the cavity between the granules. After solidification of aluminium melt the product is extracted from the mould and placed into the water, and the granules get dissolved in the water, forming pores.
EFFECT: method allows to obtain aluminium foam products with sustainable porosity and adjustable pore size.
