Ukusebenza:

I-Magnesium diboride iyinhlanganisela ye-ionic, ene-hexagonal crystal structure. I-Magnesium diboride ekushiseni okuphelele kancane okungu-40K (okulingana -233 ℃) izoguqulwa ibe i-superconductor. Futhi izinga lokushisa layo langempela lokusebenza lingu-20 ~ 30K. Ukuze sifinyelele leli zinga lokushisa, singasebenzisa i-neon ewuketshezi, i-hydrogen enguketshezi noma isiqandisi somjikelezo ovaliwe ukuze siqedele ukupholisa. Uma kuqhathaniswa nomkhakha wamanje usebenzisa i-helium ewuketshezi ukupholisa ingxubevange ye-niobium (4K), lezi zindlela zilula futhi ziyonga. Uma sekufakwe i-carbon noma okunye ukungcola, i-magnesium diboride endaweni kazibuthe, noma kukhona ukudlula kwamanje, ikhono lokugcina i-superconducting lifana ne-niobium alloys, noma lingcono nakakhulu.

Izinhlelo zokusebenza:
Ozibuthe abakhulu, imigqa yokudluliswa kwamandla kanye nezitholi zamagnetic field ezibucayi.
