Iron Simbi, FeB

Iron boride, ichangobva kuwanikwa superhard uye superconducting zvinhu, yakagadziriswa zvinobudirira murabhoritari naGou Uye vamwe vanobva kuYunivhesiti yeBayreut. Ndiyo yekutanga superconductor kugadzirwa nekombuta uye ndokugadzirwa kubva pamhedzisiro yekuverenga.

Ferric boronSimbi ye boron uye ferricIyo atomiki huremu hwe boron i10,81, chimiro chemagetsi chiri 1 $ 2p. Kuwedzera kwecristallineabout 3.8 muzana, ine yakajairika kristaro poindi, yayo eutectic tembiricha s 1? tende rboron iri 2. 31g / cm3 (20 *) uye kuwanda kweamorphous boron ndeye 2. 30g / cm3 (20 "C). Melpoint ndeye 2079", nzvimbo yekubikira iri 3660 "C Mune boron iron system, paboron boron fomu mbiri, epakati makemikari ayo zvakare akatsiga zvakanyanya patembiricha dzakakwirira .Fe2b naFeb Uye Feb ane maviri kristaro mhando: yakanyanya tembiricha uye yakaderera tembiricha. Themelting tembiricha huwandu hwemaindasitiri boron simbi (10% -20% B) iri 1400-1550C, density is5. 8-6. 5g / cm3.

Fomura yeFeB Iyo uremu hwemasero e66.66 Iron boride, ichangobva kuwanikwa superhard uye superconducting zvinhu, yakagadziriswa zvinobudirira murabhoritari naGou Uye vamwe vanobva kuYunivhesiti ye
Bayreut. Ndiyo yekutanga superconductor kugadzirwa nekombuta uye yozoitwa kubva pamhedzisiro yekuverenga., Chinese zita rekuti iron boride zita rekune dzimwe nyika Sumo yekugadzirisa Iron boride, ichangobva kuwanikwa superhard uye superconducting zvinhu, yakagadziriswa zvinobudirira murabhoritari naGou. Uye vamwe kuYunivhesiti yeBayreut. Iyo yekutanga superconductor inogadzirwa nekombuta uye wozoitwa kubva pamhedzisiro yekuverenga.Superconductor yekugadzirisa Superconductor ndiye conductor inopa zero kuramba pane yakapihwa tembiricha. Zero kuramba uye diamagnetism yakazara zvinhu zviviri zvakakosha zvinhu zvevanyanyisa.
Iyo tembiricha iyo kushora kwesupondonductor inoshandurwa kuita zero inonzi iyo superconducting yakaoma tembiricha, neiyo superconducting zvinhu zvinogona kuganhurirwa mune yakadzika-tembiricha uye yakanyanya-tembiricha superconductors. Iyo "yakanyanya tembiricha" pano inoenderana nemhedzisiro zero, kunyatso pasi pechando. Masayendisiti ave nenguva achitsvaga kukwidza tembiricha yakakosha yezvinhu zvakakurisa kuita, uye rondedzero yazvino yepamusoro tembiricha yeakanyanya-tembiricha superconductor ndeyeMark Planck Institute's 203K (-70 ° C).
Nekuda kwavo zero-kuramba zvivakwa, superconducting zvinhu zvine akawanda mashandisirwo mukugadzira yakasimba magineti minda, senge MRI uye yenyukireya magnetic resonance imaging.
