The absorption of carbon dioxide and water vapour by zinc oxide to form basic zinc carbonate was studied for a range of gas pressures and reaction temperatures. Water pretreatment of the oxide was found to influence the initial stages of the reaction. The CO2- and water-contents of the products varied according to the reacting conditions but in all cases a highly-disordered basic zinc carbonate was formed which showed an increase in order on ageing.

AbstractZinc Oxide crystals have historically been grown in hydrothermal autoclaves with a basic mineralizer; however, doubts have been raised about the quality of such crystals because they have often exhibited large x-ray rocking curve widths and low photoluminescence (PL) yield with large linewidths. Several ZnO crystals were grown hydrothermally and sliced parallel to the c-plane. This resulted in opposite surfaces (the C+ and C-) exhibiting pronounced chemical and mechanical differences. Different surface treatments were investigated and compared by PL both at room temperature and liquid helium temperatures, and by double axis X-ray rocking curve measurements. The high quality of hydrothermally-grown ZnO is substantiated by the narrow rocking curve widths and sharp PL peaks obtained. A critical factor in obtaining these results was found to be surface preparation.
