Iṣe:

Iṣuu magnẹsia diboride jẹ akojọpọ ionic kan, pẹlu igbekalẹ kirisita hexagonal. Iṣuu magnẹsia diboride ni iwọn otutu pipe diẹ 40K (deede si -233 ℃) yoo yipada si superconductor. Ati iwọn otutu iṣẹ rẹ gangan jẹ 20 ~ 30K. Lati de iwọn otutu yii, a le lo neon omi, hydrogen olomi tabi firiji-pipade lati pari itutu agbaiye. Ti a ṣe afiwe si ile-iṣẹ lọwọlọwọ nipa lilo helium olomi lati tutu niobium alloy (4K), awọn ọna wọnyi rọrun diẹ sii ati ti ọrọ-aje. Ni kete ti o ba jẹ doped pẹlu erogba tabi awọn aimọ miiran, magnẹsia diboride ni aaye oofa, tabi ti o kọja lọwọlọwọ, agbara lati ṣetọju superconducting jẹ bii awọn alloy niobium, tabi paapaa dara julọ.

Awọn ohun elo:
Awọn oofa Superconducting, awọn laini gbigbe agbara ati awọn aṣawari aaye oofa.
