Control rods are one of the most important components in nuclear reactors that is used to compensate for the fuel consumption and adjust the reactor. Boron carbide and boron steel have been used for control rods. Among all compositions, Dysprosium Titanate powders and ceramics have been used as shielding materials such as control rods [1]. Electrochemical method is an easy and economical method which carried out in low temperatures. In this paper, DyTi2O5 have been prepared by cyclic galvanostatically electrochemical experimental method. DyTi2O5 was obtained by cyclic cathodic electrodeposition from an additive free 0.005 M Dy (NO3)3 and TiCl4 bath. The bath temperature was 0 ○C. The electrochemical cell included a cathodic steel substrate centered between the two parallel graphite anodes. Also a power supply was used to generate the electric pulses. Deposition experiments were followed up in galvanostatic mode at current density of 25 mA.Cm-2 , duty cycle of 0/75 for 42 minutes. After the sample dried out, the deposit was scarped from the cathode and calcinated in 600 ○C. Crystal structure of and morphological characterization was explored by SEM.
