Mechanochemical Reactions of Lithium Niobate Induced by ...
Lithium niobate (LiNbO 3, 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. Dynamic light scattering and powder X-ray diffraction were used to determine the achieved particle and stone sizes, …
Induced by High-Energy Ball-Milling
Ball-milling was proved to be a successful method also for the preparation of lithium niobate. De Figueiredo et al. reported that ball-milling of Li2CO3 and Nb2O5 resulted in the formation of LiNbO3, but non-reacted starter materials also remained in the milled powder [16]. Pure LiNbO3 can still
Preparation of Lithium Niobate Nanoparticles by High ...
ABSTRACT We present investigations on the preparation of lithium niobate, LiNbO 3 nanoparticles using high energy ball-milling. Stoichiometric composition of LiNbO 3 powder was prepared by solid-state reaction method and used for ball-milling. Various milling parameter were optimized to …
