I-Nano magnesium oxide iyi-alkaline oxide evamile evamile.Ngenxa yezinga layo eliphezulu lokuncibilika elingu-2800°C kanye nezinye izici ezikhethekile nezinhle kakhulu, lingasetshenziswa emkhakheni we-ceramic othuthukisiwe.Ngokuya ngesicelo, ingahlukaniswa ngezindlela ezimbili: i-sintering eqondile ku-ceramics futhi isetshenziswe njengensiza ye-sintering kwezinye izitsha zobumba.
Ukucwilisa okuqondile kuma-ceramics
I-Nano magnesium oxide iyinto enhle kakhulu ye-ceramic eluhlaza.Ngenxa yokumelana kwayo nokushisa okuhle kanye nokumelana okuqinile nokuguguleka kwezixazululo zensimbi ye-alkali, i-magnesium oxide ceramics ivame ukufaneleka ezindaweni zokushisa eziphezulu.Ingasetshenziswa njenge-crucible yokuncibilikisa izinsimbi, futhi embonini yamandla e-athomu ibuye ifanele ukuncibilikisa i-uranium ephezulu ne-thorium.Ingasetshenziswa futhi njengomkhono wokuzivikela we-thermocouples.Ngenxa yokuthi inendawo yokuvumela amagagasi kagesi ukuba adlule, ingasetshenziswa njengekhava ye-radar kanye nezinto ezisetshenziswayo zewindi lokubonisa imisebe ye-infrared.Iphinde ibe yimpahla eluhlaza ye-piezoelectric kanye ne-superconducting materials, futhi ihambisana nemvelo futhi imelana nokugqwala komthofu.Ingase futhi isetshenziswe njengesithwali se-ceramic sintering, ikakhulukazi ukuvikela i-sintering yemikhiqizo ye-ceramic efana ne-β-Al2O3 enezinto ezibolayo neziguquguqukayo emazingeni okushisa aphezulu.
Isetshenziswa njenge-sintering yezinye izitsha zobumba
I-Nano magnesium oxide nayo ingangezwa enqubweni yokulungiselela ezinye izitsha zobumba, ezinomthelela omuhle ekwehliseni izinga lokushisa lokushintsha kwengilazi, ekwehliseni izinga lokushisa le-sintering, kanye nokwenza ngcono izici zokubona nemishini yezitsha zobumba, ngaleyo ndlela isisize sithole izinto zokwakha ze-ceramic ezisezingeni eliphakeme. .
Isibonelo, i-silicon nitride ceramics isiphenduke enye yezinto zokwakha ezithembisayo kakhulu ngenxa yamandla azo aphezulu ezinga lokushisa eliphezulu, ukumelana nokushaqeka kokushisa, nokuzinza kwamakhemikhali.Kodwa-ke, ibhondi yayo eqinile ye-covalent kanye ne-coefficient ephansi yokusabalalisa kwenza kube nzima ukuminyana kwe-sinter.Ukwengezwa kwe-magnesium oxide kungasabela ne-silica ebusweni be-silicon nitride powder ngesikhathi sokucwiliswa ukuze kwakhiwe isigaba se-silicate liquid, esingakhuthaza ngempumelelo ukucwiliswa kwe-silicon nitride ceramics.Njengamanje, izinsiza ze-sintering eziyinhlanganisela ye-MgO-Y2O3 zivame ukusetshenziselwa ukufeza ukucwiliswa kwengcindezi yasemkhathini ye-silicon nitride ceramics.
Kafushane, i-nano magnesium oxide idlala indima ebalulekile emkhakheni we-ceramic.Ingasebenza njengento eyisisekelo noma isengezo ukuze kuthuthukiswe ukusebenza kanye nokusebenza kwezitsha zobumba, ngaleyo ndlela ikhuthaze inqubekelaphambili nokuthuthukiswa kwemboni ye-ceramic.
