摘要：
We report here for the first time a novel method of preparing nano-crystalline metatitanate, MgTiO3 geikielite, with crystalline size varying from 20-40 nm. The preparation has been carried out by co-precipitation method involving titanium hydroxide and magnesium nitrate solution. The samples were characterized by using transmission electron microscopic, powder XRD and FT-IR spectroscopic studies. The sample annealed at 900 K for 2 h show ten X-ray diffraction peaks corresponding to the pure geikielite phase. FT-IR spectra of the nano-crystalline geikielite exhibit strong broad vibrational bands near 1000, 650 and 470 cm(-1) arising from normal vibrations of the TiO3 group.
