Al COMPOSITE MATERIAL REACTING WITH WATER, Al FILM REACTING WITH WATER, METHOD TO PRODUCE THIS Al FILM AND COMPONENT OF FILM-PRODUCING CHAMBER

摘要

FIELD: metallurgy.;SUBSTANCE: aluminium composite material reacting with water for production of a film onto a base contains an initial aluminium material selected from the group made of aluminium materials with purity of 2N, 3N, 4N, 5N, every of which contains Cu as an admixture to Al in the amount of not more than 40 ppm, and at least one metal selected from the group made of In and Bi, in the amount in the range from 2 to 5 wt % and from 0.7 to 1.4 wt % accordingly in terms of Al weight. Indium and/or bismuth are evenly dispersed in an aluminium composite material.;EFFECT: production of an aluminium composite material reacting with water and a film of this material, with the help of which film-producing materials containing precious metals are extracted.;7 cl, 5 dwg, 6 ex
