Nickel and Zinc Hydroxycarbonates are Precursors of Nanoscale Oxides

Abstract

The nanosized nickel and zinc oxides are popular materials for chemical and electronic industries. Wet chemistry methods are used for their production. Oxide precursors are metal hydroxycarbonates, that have a changing composition. As a result, hydroxycarbonates calcining oxides are formed. For the design of the technological process, the study of hydroxycarbonates composition is needed. In this work results of the zinc and nickel hydroxycarbonates composition study are presented by the volumetric method. Besides that, the SEM and X-ray investigations of nickel hydroxycarbonate are presented showing the shape of hydroxycarbonate and nano size of nickel oxide.
