Abstract
Superconducting YBCO particles with an average size of 1-2 μm were prepared by dry-type jet mill. It is found from the measurements of critical currents (Ic) that the superconducting transition temperature (Tc) at 91 - 92 K is obtained for the YBCO particles which have oriented and elongated grains align parallel to (003) (005) and (006) -plane. On the other hand, fine YBCO particles were prepared from high quality superconducting YBCO powders by wet - type jet mill in a high pressure flow of MEK (methyl-ethyl-ketone:CH3COCH2CH3) or toluene(C6H5CH3). As a result, the resulting particles are homogenius in MEK and fine YBCO particles show oriented and polycrystal structures with an average particle size of 164nm in diameter and with the lattice parameter of a=3.9A, b=3.5A in [001]-orientation from TEM (Transmission Electron Microscopy) - studies.
