The sequence of phase transformations of zinc hydroxide compounds with various chemical histories during hydrothermal (HT)
treatment is studied by X-ray powder diffraction and thermal analysis (TG/DTA). ɛ-Zn(OH)
2 (wulfingite) is the major intermediate in ZnO production by the HT process. The micromorphology and photocatalytic activity
of ZnO powders are studied.
