Synthetic conditions of Pb-dopet Bi-Sr-Ca-Cu-O oxide superconductors produced by a technique of a uniaxial hot-press method were investigated. The quality of samples was evaluated by mean of X-ray, SEM, density and magnetic measurements. The transport Jc observed by resistive transition at 77.3K was 7, 000A/cm2 at H=10 Oe for the hot-pressed sample.
