The effect of titanium substitution in the Bi 1.6Pb 0.4Sr 2Ca 2Cu 3− xTi xO 10+ y system

Bi 1.6Pb 0.4Sr 2Ca 2Cu 3− x Ti x O 10+ y (0≤ x≤0.3) samples were synthesized and investigated by resistance, AC susceptibility, and poweder X-ray diffraction measurements. The morphology of some samples was also studied using scanning electron microscopy (SEM). The results show that the addition of...

Summary:Bi 1.6Pb 0.4Sr 2Ca 2Cu 3− x Ti x O 10+ y (0≤ x≤0.3) samples were synthesized and investigated by resistance, AC susceptibility, and poweder X-ray diffraction measurements. The morphology of some samples was also studied using scanning electron microscopy (SEM). The results show that the addition of a small amount of titanium can greatly enhance the 2 2 2 3 phase formation, and that the largest volume fraction of this high- T c phase occurs for x = 0.1. It is believed that the Ti atoms were actually incorporated into the crystalline structure.
