PEI, Li-Zhai; PEI, Yin-Qiang; YANG, Yong  e  ZHANG, Qian-Feng. Ca2Ge7O16 nanowires grown from CaO and GeO2. Mat. Res. [online]. 2012, vol.15, n.1, pp.90-96.  Epub 29-Nov-2011. ISSN 1516-1439.

Single crystalline Ca2Ge7O16 nanowires have been synthesized using CaO and GeO2 as the raw materials. Various factors that affect the formation and size of the Ca2Ge7O16 nanowires have been analyzed. The obtained products are characterized by X-ray diffraction, transmission electron microscopy and scanning electron microscopy. The results show that the calcium germanate nanowires are composed of orthorhombic Ca2Ge7O16 phase with the length and diameter of several dozens of micrometers and about 50 nm, respectively. Hydrothermal temperature plays an important role on the formation and growth of the Ca2Ge7O16 nanowires. The formation process of the Ca2Ge7O16 nanowires is initially interpreted according to the shape evolution of the products obtained from different growth conditions.

Palavras-chave : Ca2Ge7O16 nanowires; CaO; GeO2; electron microscopy.
