Abstract Using LiNO 3 and SiO 2 as raw materials, Li 2 SiO 3 nano-powders were
synthesized via a nonstoichiometric 2: 3 Li: Si molar ratio hydrothermal reaction at 180° C for
48, 72, and 96 h in a NaOH aqueous solution system. The synthesized materials were
characterized by powder X-ray diffraction technique and Fourier transform infrared
spectroscopy. To investigate the effect of the reaction time on the morphology of the
obtained materials, the morphologies of the synthesized materials were studied by field …

Li 2 SiO 3 nanopowders were synthesized via a non-stoichiometric 2: 3 (S 1), 1: 3 (S 2), 1: 4
(S 3) and 1: 5 (S 4) Li/Si molar ratios via hydrothermal reaction for 72 h at 180° C in an aqua
solution using Li 2 CO 3 and H 2 SiO 3 as raw materials. The synthesized materials were
characterized by powder X-ray diffraction (PXRD) technique and Fourier transform infrared
spectroscopy. PXRD data showed that the crystal structure of the obtained materials is
orthorhombic with the space group of Cmc2 1. Also, to investigate the effect of the Li/Si molar …
