    摘要:

    以硝酸銀為原料，對苯二酚(C6H4(OH)2)為還原劑，鏈烷醇胺A為分散劑，用液相化學(xué)還原法制備高振實密度超細(xì)銀粉。用激光粒度分布儀測試銀粉的粒度分布與平均粒徑，用掃描電子顯微鏡(SEM)和透射電子顯微鏡(TEM)分析銀粉的形貌、粒徑和團(tuán)聚狀態(tài)，用多晶X射線衍射(XRD)儀檢測粉體的晶相。結(jié)果表明：通過調(diào)節(jié)硝酸銀的濃度、硝酸銀與還原劑的配比以及分散劑的用量等，可以實現(xiàn)對所制備球銀粒徑的控制；制備的超細(xì)銀粉為面心立方晶體結(jié)構(gòu)，呈規(guī)則球形，振實密度可達(dá)4.0 g/cm3。

    Abstract:

    The ultrafine Ag powders with relatively high tap density were prepared by a chemical reduction method using AgNO3 as raw material. Hydroquinone and chain triacontanol amine were chosen as reductant and dispersant agent, respectively. The laser fineness gage was used to investigate the grain size distribution and the average diameter of Ag powders. The morphology, grain size and agglomerating state of Ag powders was examined by SEM and TEM. The phase composition of Ag powders was characterized by XRD. The results show that the grain size of Ag powders can be controlled by adjusting the concentration of AgNO3, the ratio of AgNO3 to reductant and dispersant agent dosage. The Ag powder obtained is of face-centered cubic crystal structure with quasi-orbicular morphology. The average tap density of the silver powders is up to 4.0 g/cm3.
