The high demand of polymer composite for modern technique causes the need to create new varieties of such materials. At present, the production of a wide range of fillers and polymer matrices has already been produced, which allows the use of polymer composite materials as both structural materials and special purpose materials.
Zinc cementation by magnesium from ZnCl2+NH4Cl aqueous solutions has been investigated. The amount of magnesium has been established as 0.8–2.0 g per 1 g of conditioned zinc to obtain recovery degree 99 %. At low concentrations of Zn2+ ions (0.025–0.1 M ZnCl2) dispersed deposit is formed with nanoparticles of reduced metal; at high concentrations (0.25–0.5 M) coarse-crystalline and fern-shaped deposit is formed.
