SYNTHESIS OF (Bi_1.7Pb_0.3)Sr₂Ca₂Cu₂O₁₀ NANOMATERIAL SUPERCONDUCTOR.

The purpose of the study of the synthesis of the compound (Bi_1.7Pb_0.3)₂Sr₂Ca₂Cu₂O₁₀ is to characterize the properties of the superconductivity in the (Bi_1.7Pb_0.3)₂Sr₂Ca₂Cu₂O₁₀ when it is found as a nanocrystal in the stabilized 110 K superconducting compound, which will be induced in a single superconducting compound with the addition of lead that will substitute in the proportion of 15% of a bismuth, the final product will be characterized by XRD and SQUID.

To obtain the polycrystals of the material, solid state reaction was used with PbO, CuO, CaCO₃, SrCO₃, Bi2O₃ by reagents, which were crushed by hand with an agate mortar.
To obtain nanocrystals from the sample, the wet crushing technique will be used, which consists of placing the sample with methanol and a magnetic stirring bar for a period of 68:22 hours.

The polycrystalline and nanocrystalline products were characterized with SQUID to see their hysteresis curves interpreting whether they present superconductivity or not.
