W. Wang et al., Preparation of strontium bismuth tantalum (SBT) fine powder by sol-gel process using bismuth subnitrate as bismuth source, J MAT SCI T, 17(1), 2001, pp. 25-26
Strontium bismuth tantalum (SBT) fine power was prepared by Sol-Gel method.
Pentaethoxy tantalum, strontium acetate and bismuth subnitrate were used a
s raw materials, and were dissolved in proper order in ethylene glycol to f
orm transparent set. The mixed precursor was dried at 80 degreesC and annea
led at 800 degreesC for 1 h. Crystallized nanometer sized SBT fine powder w
as obtained and characterized by XRD.
