The formation and texture of Bi-2223 phase during sintering in a temperature gradient were investigated. Co-precipitated powders with the composition of Bi:Pb:Sr:Ca:Cu ΒΌ 1.85:0.35:1.90:2.05:3.05 were used. Samples set on a silver holder were sintered at 850 Β°C for 120 h in a vertical tube furnace wi
