Abstract

Whiskers of 2212 phase Bi2Sr2Ca1Cu2Ox were prepared by heating in air the powder-compacted pellets of melt-quenched glassy products in BiSrCaCu2Ox containing a small amount of Al2O3. The dissolved and/or physically mixed Al2O3 in the powder-compacted specimen is found to enhance the whisker formation remarkably.
