Bi1.7Ga0.3Sr2Ca2Cu3O10+y material was produced by the glass technique and the glass powders obtained then coated on to YSZ and Al2O3 substrates to fabricate 25-30 mu thick films using spray pyrolsis method. The films were then converted to glass-ceramic structure with suitable heat treatment cycles. The effects of substrates on the J(c) and the I-c anisotropy coefficients have been investigated and the results obtained were presented. (C) 2004 Elsevier B.V. All rights reserved.
