Noi ka pauka Chromium boride:
ʻO Chromium diboride kahi pūhui ionic, me ke ʻano aniani hexagonal. E hoʻololi ʻia ʻo Chromium diboride ma ka 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 ai 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.
