Abstract (EN): Superconductor thin films of the BSCCO system were deposited by aerosol-MOCVD on LaAlO3 and MgO substrates at a high deposition rate. The X-ray diffraction patterns of the deposited films reveal intergrowths between the 2212/2223 phases. The application of the precision plot model to a Bi-22(n-1)n heterostructure allowed the quantification of the intergrowths in terms of the n value (non-integer). A phase with n=2, Bi-2212 phase, is isolated from a phase with 2<n<3, meaning intergrowths between Bi-2212 and Bi-2223 phases. The n values were correlated with the compositions of the films with Sr/(Sr+Ca+Cu) compositional ratios close to 0.28 leading to a value of n near 3.
