Finely dispersed composite iron-silver powders

A thermochemical method has been used to make finely dispersed iron-silver composite powders for medical purposes. The physicochemical and biomedical properties have been examined. These Fe-Ag powders have been made with silv er mass contents of 0.1, 1, 5, and 10%, and they have been found to be resi stant to corrosion, nonpyrophoric, and bactericidal, and to have hydrophili c surfaces and to allow of thermal sterilization; during the formation of t he powders, the behavior can be traced from the magnetic characteristics ca n be controlled depending on subsequent use. The powders can be used in med icine for example for the treatment of suppurating wounds, trophic ulcers, and so on.
