Kachitidwe:

Magnesium diboride ndi gulu la ayoni, lomwe lili ndi mawonekedwe a kristalo a hexagonal. Magnesium diboride pa kutentha kwathunthu pang'ono 40K (yofanana ndi -233 ℃) idzasinthidwa kukhala superconductor. Ndipo kutentha kwake kwenikweni ndi 20 ~ 30K. Kuti tifike kutentha kumeneku, titha kugwiritsa ntchito neon yamadzimadzi, haidrojeni yamadzimadzi kapena firiji yotsekeka kuti titsirize kuziziritsa. Poyerekeza ndi makampani amakono omwe amagwiritsa ntchito helium yamadzimadzi kuziziritsa niobium alloy (4K), njirazi ndizosavuta komanso zachuma. Kamodzi ndi doped ndi carbon kapena zonyansa zina, magnesium diboride mu mphamvu maginito, kapena pali podutsa panopa, luso kusunga superconducting ndi monga niobium aloyi, kapena bwino.

Mapulogalamu:
Superconducting maginito, mizere yopatsira mphamvu ndi zowunikira zowunikira maginito.
