Abstract

In this research, the influence of molar cations ratio at barium titan synthesis by sol- gel method, have been investigated. Barium titan were prepare by direct mixing between aqueous solution of Barium ni trat and Titanium etoksida at pH ± 1,5 followed by stirring until the sol solution is formed. Gel made with stirred and heated at the temperature around 50° C and 60 °C. Concerning the observation of Ba?+ and Ti 4+ molar cation ratio in this research are 0,15 : 1; 0,16 : 1; 0,18 : 1 ; 0,20 : 1 and 0,22 1. Xerogel forms were obtained by heating of gel at temperatur 90°C. The next, annealing phase should be done for 24 hours at 700°C in order to be obtained BaTi03 powder. The synthesis product were characterized by x-ray diffraction and surface area determined with BET method in the solution. The result of x-ray diffraction show that the optimum BaTi03 powder is formed at the molar cation ratio 15 : 1. In this ratio is obtained either the surface area value 969,68 m?/gram.
