Low temperature preparation of nanocrystalline solid solution of strontium barium niobate by chemical process

[摘要] Sr_ð‘�?Ba_{1â€�?�ð�?��?}Nb₂O₆ (with ð‘�? = 0.4, 0.5 and 0.6) powders have been prepared by thermolysis of aqueous precursor solutions consisting of triethanolamine (TEA), niobium tartarate and, EDTA complexes of strontium and barium ions. Complete evaporation of the precursor solution by heating at ∼ 200°C, yields in a fluffy, mesoporous carbon rich precursor material, which on calcination at 750°C/2 h has resulted in the pure SBN powders. The crystallite and average particle sizes are found to be around 15 nm and 20 nm, respectively.
