Kev siv Zirconia hmoov
Peb muab high-purity zirconia hmoov, uas yuav siv tau nyob rau hauv ntau zaus, xws li cathode khoom ntawm lithium roj teeb, TZP qauv, hniav, lub backplate ntawm lub xov tooj ntawm tes, zirconia lub pov haum, ntawm lawv:
Siv raws li cov khoom zoo:
Cov hmoov zirconia muab los ntawm peb muaj cov yam ntxwv ntawm qhov loj me, cov khoom me me me me, tsis muaj zog agglomeration, thiab zoo sphericity.Doping nws mus rau hauv cov khoom siv cathode ntawm lithium roj teeb tuaj yeem txhim kho lub roj teeb lub voj voog kev ua haujlwm thiab kev ua haujlwm zoo.Siv nws cov conductivity, siab purity zirconia hmoov tuaj yeem siv rau kev tsim hluav taws xob hauv cov roj teeb ua haujlwm siab.Zirconia hmoov (99.99%) tuaj yeem siv los ua cov khoom siv anode rau lithium roj teeb, xws li nickel cobalt lithium manganate (NiCoMn) O2), lithium cobaltite (LiCoO2), lithium manganate (LiMn2O4).
Rau cov tswv cuab ntawm cov qauv:
TZP, tetragonal zirconia polycrystalline ceramics.Thaum tus nqi ntawm stabilizer tswj ntawm tus nqi tsim nyog, t-ZrO2 tuaj yeem khaws cia rau hauv lub xeev metastable mus rau chav tsev kub.Nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, nws muaj peev xwm ua rau t-ZrO2 theem hloov, toughen lub tsis-theem hloov ZrO2 lub cev, thiab txhim kho tag nrho cov ceramics puas kab.TZP muaj cov khoom siv zoo heev xws li lub zog siab, siab tawv, thiab hnav tsis kam.Nws tuaj yeem siv los ua hluav taws kub-resistant thiab kub-resistant structural qhov chaw.
Rau cov hniav porcelain:
Zirconia muaj zog, zoo biocompatibility, tsis muaj stimulation rau lub gingiva, thiab tsis muaj kev tsis haum tshuaj, yog li nws yog heev haum rau siv qhov ncauj.Yog li ntawd, zirconia hmoov feem ntau yog siv los ua zirconia ceramic hniav.Zirconia all-ceramic hniav yog tsim los ntawm lub computer-pab tsim, laser scanning, thiab ces tswj los ntawm lub computer program.Nws muaj cov yam ntxwv ntawm qhov pom zoo, qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom, thiab lwm yam.Nws tuaj yeem tau txais kev kho mob ntev ntev hauv kev kho mob.
Siv los ua rov qab vaj huam sib luag ntawm lub xov tooj txawb:
Hauv 5G era, teeb liab kis ceev yuav tsum yog 1-100 npaug ntawm 4G.5G kev sib txuas lus siv lub spectrum ntawm ntau tshaj 3GHz, thiab nws millimeter-yoj wavelength luv dua.Piv nrog cov hlau backplane, lub xov tooj ntawm tes ceramic backplane tsis muaj kev cuam tshuam rau lub teeb liab thiab muaj qhov sib piv, kev ua tau zoo ntawm lwm cov ntaub ntawv.Ntawm tag nrho cov ntaub ntawv ceramic, zirconia ceramic muaj qhov zoo ntawm lub zog siab, siab hardness, acid thiab alkali tsis kam, corrosion kuj, thiab siab tshuaj stability.Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm khawb tsis kam, tsis muaj teeb liab tiv thaiv, kev ua haujlwm kub zoo heev, thiab cov nyhuv zoo.Yog li ntawd, zirconia tau dhau los ua hom tshiab ntawm lub xov tooj ntawm tes khoom siv tom qab yas, hlau, thiab iav.Tam sim no, zirconia ceramic daim ntawv thov nyob rau hauv lub xov tooj ntawm tes yog tsuas yog tsim los ntawm ib tug backplate thiab ib tug ntiv tes cim daim npog phaj.
Siv los ua zirconia lub pov haum:
Kev tsim cov zirconia gemstones los ntawm zirconia hmoov yog ib qho tseem ceeb ntawm zirconia txoj kev sib sib zog nqus ua thiab daim ntawv thov.Cov hluavtaws cubic zirconia yog ib qho nyuaj, tsis muaj xim, thiab optically flawless crystal.Vim tias nws tus nqi qis, ruaj khov, thiab zoo li cov pob zeb diamond, cubic zirconia gemstones tau hloov pauv tseem ceeb tshaj plaws rau pob zeb diamond txij li xyoo 1976.
