Растворение нано-и ультрадисперсного порошка никеля в физиологических растворах

Abstract

The work is dedicated to studying the solubility of nano-and ultradispersed powders of nickel in synthetic physiological fluids. By the example of electroexplosive Ni powders with different size it was shown that dissolution degree of nickel particles increases from 2,1 -60 wt.% (275 nm) to 62,2 -84 wt.% (100 nm) in distilled water and synthetic saliva, respectievely. It was experimentally demonstrated that the reactivity of investigated nickel particles increases in the physiological solutions: "Water -synthetic saliva -lung fluid." It is shown that nano-and ultradispersed particles dissolve completely within a day in suspensions with a concentration of 50 mg/l.
