摘要：
Zinc oxide dispersions of different morphologies were obtained by aging at elevated temperatures solutions of zinc nitrate in the presence of NaOH, KOH, NH4,OH, triethanolamine (TEA) and ethylenediamine (En). Hydrothermal treatment at 150°C of the system Zn (NO3)2-NaOH (or KOH) yielded whiskers of very large axial ratios, while the precipitates formed with other bases on aging at 90°'C resulted in intertwined or spheroidal particles. The particle size and aggregation could be affected by the addition of anionic surfactants. © 1990.
