摘要
:从尾矿中回收铌、钽基氧化物。这些氧化物被用作蒸发法制备微纳米结构的起始材料。利用x射线衍射(XRD)、微拉曼光谱(micro-Raman spectroscopy)和扫描电子显微镜(SEM)对最终氧化物的形貌和晶体结构进行了表征。热处理后得到了两种氧化物的微晶，其化学计量量分别为Nb 22 O 54和k6 Ta 10.8 O 30。
Niobium oxide and tantalum oxide micro- and nanostructures grown using material recovered from mining tailings
: Niobium and tantalum-based oxides were recovered from mining tailings. These oxides were used as starting material for growing micro- and nanostructures by the evaporation method. The morphology and crystal structure of the final oxides were evaluated using X-ray diffraction (XRD), micro-Raman spectroscopy, and scanning electron microscopy (SEM). After the thermal treatment, microrods of both oxides were obtained, which presented exotic stoichiometries Nb 22 O 54 and K 6 Ta 10.8 O 30 , respectively.
