SYNTHESIS OF NANOSCALE NI AND FE POWDERS AND PROPERTIES OF THEIR COMPACTS

Nickel and iron ultrafine powders have been produced by the method of hydrogen reduction of the low-wafer hydroxides obtained by heterogeneo us interaction between solid salt and alkaline solution. The suggested method allows to obtain ultrafine powders with narrow particle size d istribution and low impurity contents. Bulk samples based on nickel an d iron ultrafine powders were produced by hot isostatic pressing and h igh-temperature gas extrusion methods.
