Qhov twg Alumina Outperforms Zirconia:
1. Tus nqi -kev ua tau zoo ntawm qhov ntsuas: Piv txwv li, zoo tib yam ceramic seals thiab rwb thaiv tsev cov khoom. Yog tias kev ua tau zoo txaus, alumina yog qhov kev xaiv pom tseeb vim nws cov nqi qis dua thiab cov nyiaj tau los ntau dua.
2. Maximum hardness nyob rau hauv abrasive ib puag ncig: Piv txwv li, cov kabmob thiab cov cuab yeej txiav. Alumina muaj zog dua thiab hnav ntau dua - tiv taus ntau dua li zirconium oxide, tab sis zirconium oxide muaj qhov tawv zoo thiab tsis yooj yim tawg. Yog li ntawd, alumina yog siv rau hauv cov xwm txheej ua kom huv si, thaum zirconium oxide zoo dua rau cov xwm txheej cuam tshuam.
3. Kev ua haujlwm ruaj khov nrog kev ua kom sov zoo: Piv txwv li, cov cua kub dissipation substrates rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob hauv lub siab -kub qhov cub, thiab siab - kub thermocouple sheaths. Alumina muaj cov thermal conductivity siab thiab nyob ruaj khov siab tshaj 1600 degree, thaum zirconium oxide qhov kev ua tau zoo tsis zoo siab tshaj 1000℃thiab muaj thermal conductivity tsawg, ua rau cov cua sov tsis zoo. Yog li ntawd, alumina yog qhov zoo dua rau siab -kub thiab cua kub dissipation- xav tau cov xwm txheej.
4. Flawless hluav taws xob rwb thaiv tsev nyob rau hauv high voltage: Alumina muaj rwb thaiv tsev zoo dua li zirconium oxide. Zirconia nthuav tawm ionic conductivity ntawm qhov kub thiab txias, yog li alumina zoo dua rau siab - kub rwb thaiv tsev. Piv txwv muaj xws li insulating bases thiab siab -voltage insulators hauv kev lag luam hluav taws xob.
5. Xyoo caum - ntev kev cia siab- tsis muaj kev laus, tsis muaj qhov xav tsis thoob: Piv txwv li, cov khoom siv ceramic sab nraum zoov thiab cov ntsaws ruaj ruaj uas raug cov dej tsis tu ncua. Alumina tsis raug kev txom nyem los ntawm qhov qis- qhov kub thiab txias teeb meem ntawm zirconium oxide thiab yuav tsis flake los yog tawg ntev - siv sij hawm, uas kuj yog ib qho zoo dua. Tsis tas li ntawd, alumina tam sim no yog qhov kev xaiv tseem ceeb rau lithium roj teeb cais txheej vim nws pheej yig thiab muaj qhov ntom ntom.
Qhov twg Zirconia Outperforms alumina:
1. Daim ntawv thov yuav tsum muaj siab toughness thiab cuam tshuam tsis kam: Piv txwv li, xov tooj ntawm tes rov qab panels, industrial ceramic bearings, thiab siab -ceev, hnyav -cov bearings. Zirconia tsis yooj yim rau chipping, thaum alumina yog nkig thiab tawg yooj yim. Nws kuj tsim nyog rau cov cuab yeej txiav; Thaum milling cam khwb cia hlau, zirconia ceramic cov cuab yeej muaj tsawg dua nti dua li cov alumina. Muaj ntau lub taub hau baseball bat taub hau thiab cov riam siv hluav taws xob yog ua los ntawm zirconia, uas tsis tshua tawg yog tias poob, thaum alumina hniav tawg yooj yim.
2. Biomedical applications: Piv txwv li, kho hniav yas thiab orthopedic implants. Zirconia muaj biocompatibility zoo, siab zog, thiab zoo toughness, ua rau nws tsis tshua muaj kev tawg hauv cov yas. Nws kuj muaj zoo translucency, uas ua rau ib tug ntau aesthetically pleasing tsos. Alumina, thaum muab qee qhov xim xim, tsis tshua txaus nyiam thiab nkig rau cov yas. Rau implant abutments, zirconia cov xim yog ze rau cov hniav ntuj, ua rau nws zoo nkauj dua li cov hlau abutments thiab muaj zog dua alumina.
3.Engineered rau Aggressive Chemical Ib puag ncig: Zirconia muaj cov kua qaub thiab alkali zoo dua li alumina. Piv txwv li, nyob rau hauv ib puag ncig muaj zog alkaline, alumina reacts nrog alkali, thaum zirconia tsis. Yog li ntawd, zirconia yog qhov tsim nyog rau corrosion - cov twj thiab cov ntsaws ruaj ruaj hauv kev lag luam tshuaj uas tuaj yeem tiv nrog cov alkalis muaj zog.
4. Nyob rau hauv daim ntawv thov kev zoo nkauj thiab kho kom zoo nkauj: Piv txwv li, cubic zirconia yog siv rau pob zeb diamond simulating hniav nyiaj hniav kub vim hais tias nws muaj ib tug siab refractive Performance index thiab zoo hluav taws kub, thaum alumina muaj ib tug tsawg refractive index thiab yog tsawg aesthetically pleasing. Tsis tas li ntawd, rau cov bezels ceramic thiab rooj plaub hauv smartwatches, zirconia muaj kev xav zoo dua, tso cai rau cov xim ntau dua, thiab tuaj yeem ua semi- pob tshab. Alumina yog nkig dhau lawm, ua rau cov ntaub nyias nyias nyias nyias.
5. Hauv kev ua haujlwm ceramic: Piv txwv li, nyob rau hauv cov electrolyte ntawm cov khoom siv roj oxide, tsuas yog zirconia muaj siab -kub oxygen ion conductivity; alumina yog ib qho insulator thiab siv tsis tau. Qhov no yog qhov yuav tsum tau ua haujlwm, yog li tsuas yog zirconia tuaj yeem siv tau. Zirconia kuj tseem siv rau oxygen sensors vim tias nws tuaj yeem hnov cov pa oxygen concentration, uas alumina tsis tuaj yeem.
Hauv cov ntsiab lus, yog tias koj xav tau tus nqi qis, siab hnav tsis kam, zoo thermal dissipation, thiab siab - kub stability, alumina yog qhov kev xaiv; Yog tias koj xav tau kev tiv thaiv kev tiv thaiv, kev ntseeg siab, kev zoo nkauj, kev tiv thaiv kom muaj zog alkalis, lossis cov cuab yeej ua haujlwm ntawm oxygen ion conductivity, zirconia yog qhov kev xaiv zoo dua!
Txawm hais tias nws yog alumina lossis zirconia, yog tias koj muaj kev xav tau,thov hu rau Yuchang Laser!
