The single phase powder YBa2Cu3O7-x was prepared via sol-gel method. T
he agglomerates of YBa2Cu3O7-x phase synthesized at 880-degrees-C and
900-degrees-C keep the shape of the particles of precursor, ultrasound
is effective in crushing of the precursor plateled particles. The usi
ng of EDTA as complex agent leads to the lower carbon content (0.044%
wt) in the final product.
