Abstract

Unidirectional crystallization of melt processed 2122 and 2223 composition in the Bi-Ca-Sr-Cu-O system has been carried out. Crystallization was controlled by heating the glass or cooling the melt using a moving furnace and a stationary sample. Fairly large oriented crystalline specimens of 2122 phases were obtained by cooling from the melt in a shallow gradient furnace. Glassy samples processed under steep gradients showed better crystallinity than those processed under shallow gradients.
