Özet

We have fabricated 40-150 nm sized MgB2 superconducting spherical powders by using a 2.4 MHz ultrasonic spray pyrolysis system and consecutive high temperature heating and powder collection chamber. Various chemical solutions, which contain Mg, B, de-ionized water, acetone and LAPSA in different concentrations and gas atmosphere, were used to obtain MgB2 superconducting powders. Microstructural, transport and magnetic characterizations of the powders were performed using XRD, SEM-EDX, R-T, M-H analysis and critical current density calculations, which is found in the range of 10(6) Acm(-2), indicating improved flux pinning properties.
