Magnesium diboride ke motsoako oa ionic, o nang le sebopeho sa kristale sa hexagonal. Magnesium diboride ka mocheso o felletseng hanyenyane 40K (e lekanang le -233 ℃) e tla fetoloa superconductor. 'Me mocheso oa eona oa sebele ke 20 ~ 30K. Ho fihlela mocheso ona, re ka sebelisa neon ea metsi, hydrogen e metsi kapa sehatsetsi se koalehileng ho qeta ho pholile. Ha ho bapisoa le indasteri ea hona joale e sebelisang helium ea metsi ho pholisa alloy ea niobium (4K), mekhoa ena e bonolo haholoanyane ebile e na le moruo. Hang ha e kenngoa ka carbon kapa litšila tse ling, magnesium diboride ka matla a khoheli, kapa ho na le ho feta hona joale, bokhoni ba ho boloka superconducting bo tšoana le li-alloys tsa niobium, kapa ho feta.
