“…Initially it was proposed for the glassy pellet methods [12]; quenching of the melt is done between metal blocks, as already introduced, but in this case surface of the metal is covered with scattered Al 2 O 3 powder. Whiskers also grow if Al 2 O 3 powder is directly scattered on the surface of the powder pellets [13]. An advanced version was recently reported, area controlled growth, in which seeding is realized through deposition in vacuum of a flux-layer on the surface of the substrate through an Au-mask.…”

We review the current status of the growth, characterization and applications of Bi-Sr-Ca-Cu-O (BSCCO) whiskers from the materials science point of view. Our analysis leads to the conclusion that reconsideration of the importance of the whisker studies is necessary; whiskers can play a major role in studies of the growth mechanism and defects, properties control and their understanding, and new devices and applications. Arguments favourable to the idea that BSCCO whiskers can possibly have a significant impact on future synthesis of nano-objects in this system or other high-T c superconducting systems, as well as in investigation and understanding of the growth processes under elevated magnetic fields, are discussed. Emphasis is made on superconducting whiskers, but non-superconducting ones are also briefly addressed.

“…Observation of microscopic void and cracks inside the treated pellet in close proximity with the (Ba,Ca) 3 TeO 6 phase also supports our proposition. Our observations suggest that the whisker growth by annealing Ca and Te doped stoichiometric sintered precursor (both Bi-2212 and R-123) has a different mechanism than micro-crucible growth model [8,[12][13][14] but has similarity with the ''inner-stress'' model [16].…”

“…Tm, Yb and Lu) single crystalline whiskers [5][6][7]. Various growth mechanisms for whiskers are proposed for high-T c superconducting materials but all these mechanisms fall into two broad groups [8]. One is where vapor phase transport is essential and whiskers grow by a tip-growth mechanism [9][10][11].…”
