Hana:

ʻO ka Magnesium diboride kahi hui ionic, me ke ʻano aniani hexagonal.E hoʻololi ʻia ka Magnesium diboride ma kahi wela piha 40K (e like me -233 ℃) i superconductor.A ʻo kona mahana hana maoli ʻo 20 ~ 30K.No ka hiki ʻana i kēia mahana, hiki iā mākou ke hoʻohana i ka neon wai, ka hydrogen wai a i ʻole ka pahu pahu pahu pani e hoʻopau ai i ka hoʻoilo.Ke hoʻohālikelike ʻia i ka ʻoihana o kēia manawa e hoʻohana ana i ka helium wai e hoʻomaha ai i ka alloy niobium (4K), ʻoi aku ka maʻalahi o kēia mau ʻano hana.I ka manawa e hoʻopaʻa ʻia me ke kalapona a i ʻole nā ​​​​mea haumia ʻē aʻe, magnesium diboride i loko o kahi māla magnetic, a i ʻole he hala i kēia manawa, ʻo ka hiki ke mālama i ka superconducting e like me nā alloys niobium, a ʻoi aku ka maikaʻi.

Nā noi:
Nā mākēneki superconducting, nā laina hoʻoili mana a me nā mea ʻike mākaʻikaʻi koʻikoʻi.
