| Abstract: | Crystalline silica powders were prepared by the molten salt method with tetraethoxysilane as raw material, NaCl and KCl as fluxing agent and catalyst.The structures were characterized by XRD and SEM.Effects of process parameters on properties were studied.The results indicated that the crystallinity and microstructure of the silica powder were influenced by the reaction temperature and mole ratio of molten salt. |
