Preparation of Sb3Nb3O13 powders using molten salt method

The powders of pure cubic phase of Sb3Nb3O13 were obtained using molten salt method at 1,100 C with incubation time of 3 h. The formation of a kind of compound with hydroxyl restrains the volatilization and oxygenation of antimony oxides. The powder of cubic Sb3Nb3O13 shows octahedral shape and its size lies between 1 lm and 20 lm. Densified ceramic was obtained using the Sb3Nb3O13 powders. The microstructure of ceramic samples was studied by XRD and SEM analysis. And the dielectric properties as a function of frequency and temperature were measured between 25 C and 550 C and 100 Hz~1 MHz.
