Magnesium diboride wani fili ne na ionic, tare da tsarin crystal hexagonal. Magnesium diboride a cikakken zafin jiki dan kadan 40K (daidai da -233 ℃) za'a canza shi zuwa superconductor. Kuma ainihin zafin aikinsa shine 20 ~ 30K. Don isa wannan zafin jiki, zamu iya amfani da neon ruwa, hydrogen ruwa ko firiji mai rufewa don gama sanyaya. Idan aka kwatanta da masana'antu na yanzu ta yin amfani da helium na ruwa don kwantar da niobium alloy (4K), waɗannan hanyoyin sun fi sauƙi da tattalin arziki. Da zarar an ɗora shi da carbon ko wasu ƙazanta, magnesium diboride a cikin filin maganadisu, ko kuma akwai wucewa ta halin yanzu, ikon kula da abin da ya fi dacewa ya kai kamar niobium alloys, ko ma mafi kyau.
