| 摘 要： | 利用螯合物分解法制备了ＺｎＯ微粉，选用的螯合剂有氢氧化铵，乙二胺四乙酸二钠和疏基丙氨酸。实验结果表明，由于Ｚｎ－ＮＨ３络离子的稳定常数小，所得ＺｎＯ粒子直径大，而当络离子的稳定常数适当时可得到纳米级微粉粒子。

| Abstract: | The zinc oxide powders have been prepared by decomposition of zinc ammine and zinc chelates. The NH 4OH as complexing agent and the ethylene diamine tetra-atomic acid disodium salt, L Cysteine as chelating agent were used. The experimental results show that the nanometre size ZnO powders were obtained when the metal chelates have a medium stability constant. |
