Lithium niobate powders were prepared by mechanochemical treatments using Li2CO3 and Nb2O5 as raw materials. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) were employed to evaluate the morphologies and structures of samples. The mechanism of LiNbO3 formation of the ground mixture samples was discussed.
Abstract: Lithium niobate (LiNbO3, LN) nanocrystals were prepared by ball-milling of the crucible residue of a Czochralski grown congruent single crystal, using a Spex 8000 Mixer Mill with different types of vials (stainless steel, alumina, tungsten carbide) and various milling parameters.
Congruent lithium niobate (Li/Nb=48.6/51.4) powders were prepared from high-purity Li2CO3 (99.99%) and Nb2O5 (99.995%). They were mixed in a polypropylene (PP) can in an alcohol-wetted ZrO2 ball mill for 24h. After the mixture was dried and calcined at 800℃ with a 24h de-carbonization and solid state
