Abstract
From the study of the Bi(2223) phase formation mechanism on pressed pellets of the Pb stabilized (Bi,Pb)2Sr2Ca2Cu3O10+d compound it was concluded that a nucleation and growth mechanism is suitable to describe the transformations occurring in air. This was concluded from observation by SEM of the transformations occurring on a fixed location at the surface of a pellet after several heat treatments at the reaction temperature, 852°C.
