文摘
We report a simple hydrothermal slow cooling process to synthesize zinc hydroxide chloride (ZHC)powders consisting of large-sized single-crystal sheets. The lateral size of the sheetlike products can betuned from 20 to 500 
m through the control of pH condition of the starting zinc chloride solution andthe amount of the solute. The growth mechanism of the ZHC sheets is explained by dissolution at hightemperatures and precipitation during slow cooling. The ZHC single-crystal sheets were converted tohighly oriented polycrystalline zinc oxide sheets by calcination at 500 
C for 5 h in air.
