Abstract (2. Language): 
In this work, superconducting pellets without lead (Pb) as well as with different concentrations of lead are prepared by solid state reaction. The prepared samples are then characterized using X-ray powder diffraction (XRD), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDX). The superconducting properties are examined using electrical resistivity and transport critical current density Jc. Our results show that the sample prepared with calcination of 48 hours with intermediate grinding has the ideal value of the superconducting transition temperature Tc and transport critical current density Jc.
Abstract (Original Language): 
Bu çalışmada, hem kurşun bulundurmayan süper iletken tabletler hem de farklı kurşun kombinasyonları bulunduran tabletler katı hal reaksiyonuyla hazırlandı. Hazırlanan örnekler X ışını toz dağılımları kullanarak (XRD), elektron mikroskobu (SEM) ve enerji dağıtıcı X ışını spektroskopisi ile taranarak karakterize edildi. Süper iletken özellikleri elektrik direnci ve kritik akım yoğunluğu transferi Jc kullanılarak incelendi. Sonuçlarımıza göre 48 saat orta derecede öğütülen kalsinasyonla hazırlanan örneğimiz ideal süper iletken geçiş ısısı Tc ve kritik akım yoğunluğu transferi Jc değerlerine sahiptir.
