Description
D.C. electrical properties of Bi2VO5.5 ceramic was measured.
The polycrystalline Bi2VO5.5 ceramic was synthesised via a conventional solid state reaction route. The stoichiometric mixture of initial powders of Bi2O3 and V2O5 were ball-milled in pure acetone for 6 h. The milling was performed in steps of 1 h with rest intervals of 10 min. The mixture was initially heated up to 770 K and then to 1020 K in air. It was kept at this temperature for 24 h and grinded next. The calcined powder was mixed with a small amount of ethyl alcohol binder and cold-pressed into pellets (12 mm in diameter and 2–3 mmin thickness) under a compacting pressure of 26 kNcm−2. The obtained pellets were sintered at 1070 K for 24 h with heating and cooling rates of 50 Kh−1.
For the electrical measurements gold electrodes were evaporated at the preheated samples. D.C. measurements were carried out with the use of Hioki 3522–50 LCR HiTester. Measurements were done in temperature range from 370 K to 920 K in air atmosphere. The temperature was controlled with the use of high temperature Novotherm HT 1600.
