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 ti ni doped pẹlu erogba tabi awọn aimọ miiran, magnẹsia diboride ni aaye oofa, tabi ti o wa lọwọlọwọ kọja, 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.
