FIELD: powder metallurgy. SUBSTANCE: invention, in particular, relates to charge compositions for preparing porous permeable material involving self- propagating high-temperature synthesis technique. Charge contains, wt %: iron dross 41-43, alumina 37-40, ferrosilicium 1-5, and aluminum - the balance. Material is appropriate for manufacturing filter elements, fire extinguishers, aerators, and other porous items. EFFECT: increased resistance for dynamic loadings in products and reduced usage of metal. 1 tbl
