【摘要】 论述了草酸盐热分解法制备超细ＺｎＯ粉体的工艺，讨论了粉体制备过程中沉淀条件、不同热分解温度以及热分解时间对超细ＺｎＯ特性的影响，并在９００℃２ｈ制得了原生粒子为４０～６０ｎｍ、聚集状态为极为少见的“短穗状”“镂空”集合体的ＺｎＯ超细粉体。更多还原

【Abstract】 The technology of ZnO ultrafine powder prepared by oxalate thermal decomposition methods was studied in detail.The influences of depositing condition, different thermal decomposing temperature and time on the characteristics of ZnO ultrafine powder were discussed.Finally,ZnO ultrafine powder which gathered hollow or like short spike was prepared in 90 ℃ for 2 h with diameter between 40 nm and 60 nm.更多还原
