Single phase of orthorhombic Li 2 SiO 3 was synthesized via a novel soft-chemical synthesis method, water assisted solid state reaction method at 343353 K for 60 min. The crystal structure of the samples was characterized by X-ray diffraction (XRD) analysis. The scanning electron microscope (SEM) observation revealed that the estimated size of the particles is 50200 nm. The XRD patterns and SEM images were compared to those of samples by a conventional solid state method at 1173 K for 4 h.
