Abstract

Studies of solids evolution during oxidation of powdered Co(OH)2 to CoOOH by oxygen in air flow or water suspension have been carried out at different temperatures by electron microscopy and diffraction.

Although the same mechanisms are operating, changes of habit and texture of reacting particles are temperature and medium dependent. As the case may be, the particles will be porous without habit change or broken up into flakes with or without orientation relationships.
