Strontium bismuth tantalum (SBT) fine power was prepared by Sol-Gel method. Pentaethoxy tantalum, strontium acetate and bismuth subnitrate were used as raw materials, and were dis- solved in proper order in ethylene glycol to form transparent sol. The mixed pr.cursor was dried at 80deg.C and annealed at 800deg.C for 1 h. Crystallized nanometer sized SBT fine powder was obtained and characterized by XRD.
