Magnesium diboride shine mahaɗin ionic tare da kyakkyawan tsarin lu'ulu'u. Abu ne mai laushi da wahala tare da rashin karfin aiki. Yana da haɗin haɗin kai. Ana shirya matakan magnesium da boron a madadinsu. Zai canza zuwa superconductor a zafin jiki dan kadan kusa da cikakken zafin jiki na 40K (watau - 233 ℃). Yanayin zafinsa ya ninka sau biyu kamar na sauran manyan masanan manyan nau'ikan nau'ikan, kuma ainihin zafin aikinsa yakai 20 ~ 30K. Babban yanayin zafin yanayi na MgB2 shine 39K, wato ya rage 234 ℃, wanda shine mafi girman yanayin zafin jiki na manyan masu sarrafa ƙarfe. A matsayin sabon abu tare da karfin aiki, magnesium diboride yana bude wata sabuwar hanya don nazarin sabon ƙarni na semiconductor mai zafin jiki mai sauƙi tare da tsari mai sauƙi. Superconductor magnesium diboride wani ƙarfe ne wanda aka ƙirƙira shi ta haɗin magnesium da boron a cikin kimar 1: 2. An halicce shi da wadatattun albarkatu, ƙarancin farashi, haɓakar haɓaka, haɗuwa cikin sauƙi da aiki mai sauƙi.

Saboda MgB2 yana da sauƙin yin fim da wayoyi na bakin ciki, ana iya amfani dashi sosai wajen ƙera CT scanners da sauran kayan aikin lantarki, ɓangarorin manyan kwamfyutoci da kayan aikin watsa wutar lantarki. Yana da fa'idar aikace-aikace mai faɗi a fagen lantarki da kwamfuta. An sami nasarar kirkirar wani nau'ikan samfurin MgB2 mai karfin gaske wanda aka hada shi da zafin jiki mai karfi da kuma matsin lamba a kasar China, wanda yake kusa da matakin kasa da kasa. Aikace-aikacen da ake amfani da su na MgB2 sun haɗa da maganadisun sarrafa abubuwa, layukan watsa wutar lantarki da masu gano filin maganadisu masu mahimmanci. A cikin 2001, masu bincike sun gano cewa wani fili mara kyau, magnesium diboride, ya canza zuwa superconductor a zafin jiki dan kadan kusa da cikakken zafin jiki na 40K (- 233 ℃). Yanayin canjin nasa ya ninka sau biyu kamar na sauran manyan masanan na wannan nau'in, kuma ainihin zafin aikinsa yakai 20 ~ 30K. Don cimma wannan zafin jiki, ana iya amfani da ruwan neon, hydrogen na ruwa ko firinji zagaye na ruhu don sanyaya yanayin.

Idan aka kwatanta da sanyaya na masana'antar niobium alloy (4K) tare da helium na ruwa, waɗannan hanyoyin suna da sauƙi da tsada. Da zarar an shaƙe shi da iskar carbon ko wasu ƙazamta, ƙarfin magnesium borate don kulawa da haɓaka ba ƙarancin na niobium ba ne ko ma mafi kyau a yanayin magnetic ko halin yanzu. Abubuwan aikace-aikacen da zasu iya amfani da su sun hada da maganadisu masu saurin sarrafawa, layukan watsa wutar lantarki da kuma masanan filin maganadisu masu matukar muhimmanci.
