Magnezyum diborür (MgB2)
süperiletken külçe malzemeleri argon atmosferinde ex-situ (hazır toz) ve
in-situ (Mg+2B) katıhal reaksiyon yöntemiyle hazırlanmıştır. Ex-situ/in-situ
MgB2 süperiletken örneklerin bir yüzeyine ~50 µm altın (Au) kalın
film kaplaması yapılmıştır. Bir yüzeyi Au kaplı ex-situ/in-situ MgB2
süperiletken örnekler 650oC–850oC sıcaklık aralığın da 1
saat tavlanmıştır. Bu malzemelerin X-Işını Kırınım (XRD) yöntemi kullanılarak
mikro yapısal değişimi ve direnç-sıcaklık ölçümleri (R-T) ile elektriksel
karakteristiği incelenmiştir. Au kaplamasıyla MgB2 malzemesinin c örgü
parametresi ve özkütlesinin arttığı gözlenmiş, aynı zamanda bazı tavlama
sıcaklığında kritik geçiş sıcaklığı (Tc) iyileşme göstermiştir.

Magnesium
diboride (MgB2) superconducting bulk materials were prepared by the
ex-situ (commercial powder) and in-situ (Mg + 2B) solid state reaction method
in argon atmosphere.
One surface of
the ex-situ / in-situ MgB2 superconducting samples was coated ~50 μm
gold (Au) thick film. Au-coated surface of ex-situ / in-situ MgB2
superconducting samples was annealed at temperature range from 650oC
to 850oC for 1 hour. The microstructural properties and electrical
characteristics of these materials were investigated by X-Ray Diffraction (XRD)
method and resistance-temperature measurements (R-T), respectively. It has been
found that the lattice parameter c and density of MgB2 material were
increased by coating Au, also the critical transition temperature (Tc)
was improved at some annealing temperatures.
