Ceramic formula ufa ndi malo opangira mlcc, yowerengera 20% ~ 45% ya mtengo wa MLCC. Makamaka MLCC ili ndi zofunikira kwambiri pa chiyero, kukula kwa tinthu, granulogy ndi morphology ya ufa wa ceramic ufa, ndi mtengo wa maakaunti a ceramic ufa wofanana. MLCc ndi mawonekedwe apakompyuta a eleramic opangidwa ndi kuwonjezera zowonjezera zowonjezerabarium cananate ufa, omwe amatha kugwiritsidwa ntchito mwachindunji ngati diect mu mlcc.
Dziko lapansindi zinthu zofunika kwambiri za mlcc mefelelert. Ngakhale amawerengera ndalama zosakwana 1% ya zida zomera mliko, amatha kuchita mbali yofunika kwambiri posintha malo okhala mlinji. Ndi amodzi mwa zinthu zofunika kwambiri pakupanga ma faur-kumapeto kwa mlcc ceramic ufa.
1. Kodi ndi zinthu ziti zosowa zapadziko lapansi? Zinthu zamtundu wapadziko lapansi, zomwe zimadziwikanso kuti zitsulo zapadziko lapansi zapadziko lapansi, ndi gawo lalikulu la zinthu za Lantanide ndi magulu aing'ono padziko lapansi. Ali ndi zida zamagetsi zapadera komanso zamankhwala, ndi zamagetsi zamagetsi, zowoneka bwino, zamatsenga, ndi mafuta opangira chuma amadziwika kuti chuma chatsopano cha zatsopano.
Zinthu zapadziko lapansi zaing'ono zamiyala zagawidwa: Zinthu zowala zapadziko lapansi (zokhala ndi manambala atomiki atomiki):sinandium(SH),YNTrium(Y),Lanthanum(LA),ceum(CE),Praseymium(Pr),Newdyoum(ND), Promethium (PM),mhamarium(SM) ndiEuropium(EU); Zinthu zolemera zamiyendo zapadziko lapansi (ndi manambala akulu atomiki):gadolinium(GD),mnyanga(TB),Dysprium(Dy),Holmium(Ho),Erbium(Er),mapelium(TM),yterbium(Yb),lutetium(Lu).
Dziko lapansi ma olima amagwiritsidwa ntchito kwambiri mu ceramics, makamakaCerium Oxide, Lanthanum oxide, Newdymium oxide, Dysprium oxide, Samarium Oxide, Holmium oxide, Erbium oxide, etc. Kuonjezera kuchuluka kochepa kapena kupenda dziko lapansi zopanda pake kungasinthe micramics, gawo, kachulukidwe, makina, makina, mphamvu ndi mankhwala osokoneza bongo.
2. Kugwiritsa ntchito dziko lapansi ku mlccBarum Titanatendi imodzi mwazinthu zazikulu zopangira mlc. Barum Titanate ali ndi pizzoelectric, ferroelectric ndi diectric katundu. Barium wa barium Titanate imakhala ndi kutentha kwakukulu kokwanira, kutentha kwambiri kuchimwa komanso kutayika kwakukulu kwa dielect, ndipo sikuyenera kugwiritsa ntchito mwachindunji popanga capoctor.
Kafukufuku wawonetsa kuti ma serilecle a barlectic of barium Tinanate amagwirizana kwambiri ndi mawonekedwe ake a kristalo. Kudzera pachimake, kapangidwe ka aryaul tiananate kungayendetsedwe, potengera ndalama zake zonse. Izi ndizomwe zimapangidwa ndi barium cansayate idzapanga kapangidwe ka zipolopolo mutatsika, omwe amatenga gawo lofunikira pakuwongolera matenthedwe a kukula kwa mphamvu.
Zinthu zomwe zimachitika padziko lapansi pano zomwe zidachitikira mu barium tiyani ndi njira imodzi yosinthira machitidwe ochiritsira ndi kudalirika kwa MLCC. Kafukufuku wazithunzi zapadziko lapansi ya Ion yemwe adatsitsa Barium Tinachate akhoza kutumizidwanso kumayambiriro kwa 1960s. Kuphatikiza kwa dziko lapansi osowa kumachepetsa kusuntha kwa okosijeni, komwe kumawonjezera kutentha kwa sekondale komanso kusakaniza kwamagetsi kwa ma sentimics, ndikusintha magwiridwe antchito komanso kudalirika kwa zinthu. Dziko lomwe anthu ambiri okonda kwambiri limaphatikizapo:YTTRIAM OXID(Y2o3), Dysprium oxide (Dy2o3), Holmium oxide (Hoo2o3), etc.
Kukula kwa ma radius padziko lapansi wamba kuli ndi kofunikira kwambiri pa malo a cuerie tinthu tamanitate zozizwitsa. Kutsitsa nyama zamtundu wina ndi radidi osiyanasiyana kumatha kusintha magawo a makhiristo okhala ndi nyumba zowonekera za zipolopolo, potero akusintha mbola yamkati yamakziro. Kutsitsa zachilengedwe kwambiri padziko lapansi ndi radii yayikulu kumabweretsa mapangidwe a pseudosubic magawo ndi zipsinjo zotsalira mkati mwa makhiristu; Kukhazikitsidwa kwa osowa kwambiri padziko lapansi okhala ndi radio yaying'ono kumatulutsa kupsinjika pang'ono mkati ndikuyika kusintha kwa gawo mu chipolopolo. Ngakhale ndi zowonjezera zazing'ono, mawonekedwe a dziko lapansi osowa, monga tinthu tating'ono kapena mawonekedwe, zitha kukhudzidwa kwambiri ndi momwe zinthu ziliri kapena mtundu wa malonda. MLCC yogwiritsira ntchito mokhazikika imangopanga miniaturization, kuthira kwambiri, mphamvu yayikulu, kudalirika kwakukulu, ndi mtengo wotsika. Zinthu zodulidwa kwambiri padziko lonse lapansi zalowa, ndipo dziko lapansi la ossozis, monga zinthu zofunika kwambiri, ziyenera kukhala ndi Nanoscale tinthu kukula ndi ufa wabwino wobalalitsa.
