Zirconium oxide muaj ntau yam muaj txiaj ntsig zoo uas ua rau nws haum rau ntau lub hom phiaj thoob plaws ntau qhov kev lag luam. Cov txheej txheem zirconia raug tsim thiab kho cov txheej txheem ntxiv tso cai rau lub tuam txhab txhaj tshuaj zirconia los hloov nws cov yam ntxwv kom haum rau cov kev xav tau tshwj xeeb thiab cov kev xav tau ntawm ntau tus neeg siv khoom thiab kev siv sib txawv.
Hauv qhov kev hwm, zirconia zoo ib yam li alumina. Thaum txhuas oxide ua haujlwm rau ntau lub hom phiaj, alumina tuaj yeem dhau los ua ntau yam kev tsim khoom thiab kev kho mob kom tau raws li ntau yam kev xav tau. Txawm li cas los xij, kev siv, kev siv, thiab cov yam ntxwv yuav txawv. Tshawb xyuas cov ntawv thov thiab hardness ntawm zirconium dioxide.
Zirconium oxide (ZrO2), los yog zirconia, yog ib qho khoom siv ceramic uas feem ntau siv los tsim ntau hom khoom siv hluav taws xob ruaj khov. Vim nws hardness, tshuaj unreactivity, thiab ntau yam biocompatible yam, cov khoom no pom dav siv nyob rau hauv zus tau tej cov ntau yam hniav implants.
Zirconia tsuas yog siv cov hniav zoo nkauj tshaj plaws ntawm cov khoom siv ceramic no. Muaj lwm yam khoom uas ua rau zirconia haum rau ntau yam kev siv. Cov khoom no muaj xws li:
Cov khoom pov thawj zoo heev tiv thaiv corrosion thiab ntau yam tshuaj
Chav-kub lub zog yog siab heev
High tawg toughness
High hardness thiab ntom
Zoo heev hnav tsis kam.
Kev sib txhuam zoo.
Tsawg thermal conductivity
Khoom hluav taws xob rwb thaiv tsev
Cov no thiab lwm yam ntxwv ua rau zirconium dioxide yog cov khoom siv nrov rau kev kho hniav thiab lwm yam lag luam. Zirconia kuj tseem siv rau hauv:
Kev tuav dej
Aerospace Cheebtsam
Cov cuab yeej txiav
Biomedical applications
Micro engineering
Cov khoom siv hluav taws xob
Fiber optics
Nozzles rau txau thiab extrusion
Cov khoom uas thov kom pom qhov pom kev txaus siab
Cheebtsam nrog lub zog siab thiab hnav tsis kam
Nws yog hom versatility uas ua rau zirconia yog ib qho ntawm cov khoom siv ceramic tshaj plaws. Dab tsi ntxiv, cov tuam txhab muaj peev xwm tsim tau ntau yam sib txawv thiab cov khoom siv los ntawm zirconia siv kev txhaj tshuaj molding, tso cai rau nws los ua ib qho khoom siv ntau dua.
