Popis:	In this work we studied the synthesis of BSCCO-2212 superconducting phase associating a quite similar method developed by Pechini (PM) with the microwave-assisted hydrothermal method, MAH. To study the influence of MAH on the properties of BSCCO system, we synthesized two samples by such method. For one sample we used carbonates (CMAH) and for the other one we used nitrates (NMAH) as chemical reagents. We also produced a reference sample (REF) just using carbonates by PM to compare their morphological and superconducting properties. The structural properties of the samples were analyzed by scanning electron microscopy and X-ray diffraction. It can be noted that the Bi-2212 phase is predominant in all samples; MAH samples present larger grains than the REF one. However, we can observe that the magnetic behaviour of NMAH is closer to that presented by REF. Comment: 4 pages, 5 figures, work presented in EUCAS 2013
