Co-Doped Barium Strontium Titanate

Nanostructures of pure barium strontium titanate (BaSrTiOs), Bai- Sr TiOs (where a = 0.1, BIOST), and Bai Sr Tii j,COj,03 (where r = 0.1 and 3 =0.1, BIOSTIOC) were prepared as powders by a modified sol-gel method. 

The samples were prepared using barium acetate (Ba(Ac)2), Sr(Ac)2, and titanium butoxide (Ti(OC4H9)4) as the starting materials acetylacetone (AcAc, C5H8O2) and acetic acid (HAc)-H20 mixture were used as solvents of Ti(OC4H9)4 and Ba(Ac)2, respectively. Cobalt nitrate was added to the final solution with a molar ratio of 10 mol%. Crystallization of the gel was achieved by thermal treatment in air for 4 h at 850 °C [102].
