Hloov ntawm Peb Cov Ntawv Cuam Tshuam ntawm Ceramic Heater Zirconia

Hauv kev lag luam ceramic rhaub, zirconia yog cov khoom siv feem ntau rau nws cov thermal zoo heev thiab txhua yam khoom. Txawm li cas los xij, zirconia muaj nyob rau hauv peb hom siv lead ua sib txawv: monoclinic, tetragonal, thiab cubic, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub tshuab rhaub ceramic. Nov yog qee cov lus nug thiab cov kev daws teeb meem hais txog kev hloov pauv ntawm peb cov ntaub ntawv siv lead ua ntawm ceramic rhaub zirconia.

1. Vim li cas zirconia hloov nws daim ntawv siv lead ua?

Cov qauv siv lead ua ntawm zirconia feem ntau cuam tshuam los ntawm qhov kub thiab txias thiab cov ntsiab lus ntawm stabilizing cov neeg ua haujlwm. Ntawm qhov kub thiab txias, zirconia nyiam tsim cov khoom siv lead ua monoclinic, uas tsis tshua muaj kev ruaj khov thiab ua rau tawg. Raws li qhov kub thiab txias, monoclinic zirconia hloov mus rau tetragonal zirconia thiab tom qab ntawd mus rau hauv cubic zirconia, uas muaj kev ruaj ntseg thiab lub zog ntau dua.

2. Yuav ua li cas hloov cov ntaub ntawv siv lead ua cuam tshuam rau kev ua haujlwm ntawm ceramic rhaub?

Cov qauv siv lead ua sib txawv ntawm zirconia muaj qhov sib txawv thermal expansion coefficients thiab hluav taws xob conductivity, uas ncaj qha cuam tshuam rau kev ua haujlwm ntawm ceramic rhaub. Piv txwv li, cubic zirconia muaj qhov qis tshaj thermal expansion coefficient thiab siab tshaj plaws hluav taws xob conductivity, uas ua rau nws zoo tagnrho rau high-temperature daim ntaub ntawv. Ntawm qhov tod tes, monoclinic zirconia yog qhov tsim nyog rau cov ntawv thov kub qis vim tias nws cov thermal expansion coefficient siab thiab qis hluav taws xob conductivity.

3. Dab tsi yog cov kev daws teeb meem los tswj cov qauv siv lead ua ntawm zirconia hauv ceramic rhaub ntau lawm?

Ntxiv cov tshuaj stabilizing xws li yttrium oxide los yog magnesium oxide tuaj yeem tswj cov khoom siv lead ua ntawm zirconia thiab txhim kho nws cov kev ua tau zoo. Tsis tas li ntawd, kho qhov kub thiab txias thiab lub sij hawm kuj tuaj yeem cuam tshuam rau daim ntawv siv lead ua thiab txhim kho qhov zoo ntawm cov khoom siv hluav taws xob ceramic.

Hauv kev xaus, kev nkag siab txog kev hloov pauv ntawm peb cov qauv siv lead ua ntawm ceramic rhaub zirconia yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm ceramic rhaub. Los ntawm kev siv cov txheej txheem ruaj khov kom zoo thiab ua tib zoo tswj cov txheej txheem sintering, cov tuam ntxhab ceramic tuaj yeem tsim cov khoom lag luam txhim khu kev qha thiab ruaj khov uas ua tau raws li cov kev xav tau ntawm ntau hom kev siv.
