8 Mol feem pua ​​Yttria Stabilized Zirconia Crucible

8 mol feem pua ​​Yttria Stabilized Zirconia Crucible Description

The system of Y2O3-ZrO2 has been extensively studied for more than 50 years. Most of the early publications deal with YSZ as structural ceramic material at various Y contents (mainly below 7 mol% Y2O3 ). A fully (cubic) stabilized zirconia is obtained with a Y2O3-content of >7 mol feem pua, thaum ib tug Y2O3-cov ntsiab lus ntawm txog 2-6 mol feem pua ​​muab ib feem stabilized zirconia.

Tag nrho yttria stabilized zirconia (8 feem pua ​​​​ntawm mole yttria) ceramics yog siv thaum daim ntawv thov yuav tsum muaj lub crucible uas muaj zog heev, hnav-resistant thiab chemically inert ntawm qhov kub siab heev. Nws kuj yog cov khoom siv rau feem ntau cov ntawv siv biocompatible. Tag nrho yttria stabilized zirconia yog cov khoom siv nrog lub zog siab dua los ntawm cov ntaub ntawv uas peb muab thiab nthuav tawm lub zog flexural uas siab dua nitrides thiab tuaj yeem ncav cuag tus nqi ntawm carbides. Cov cuab yeej no txuas ntxiv kev ntseeg tau thiab lub neej ntawm crucibles ua nrog zirconia stabilized.

Siab yttria stabilized zirconia technical ceramics muaj qee qhov zoo dua alumina. Namely, tag nrho yttria stabilized zirconia crucibles piv rau alumina crucibles yog ntau refractory thiab qis thermal conductivity, muaj zoo dua nto tiav, yog denser thiab yog txawm 4 npaug superior nyob rau hauv cov nqe lus ntawm lub zog (cov cuab yeej no degrades thaum kub exhibits 1000 degree). Txawm li cas los xij, lawv tseem kim kim dua li qib siab tshaj ntawm alumina thiab tsis tshua muaj thermal shock resistant. Lub ntsiab yog vim li cas rau 8YSZ tus nqi siab yog tias ob qho tib si zirconia thiab yttria raw khoom tsis tshua muaj piv nrog alumina.

Nws yuav tsum raug sau tseg tias zirconia tuaj yeem ua rau muaj kev cuam tshuam rau chemisorption nyob rau hauv lub xub ntiag ntawm dej molecules, yog li YSZ zog degrade sai heev thaum raug dej vapor ntawm 200-300 degree .

Peb muaj pes tsawg leeg rau YSZ suav nrog 3mol feem pua, 5mol feem pua ​​thiab 8mol feem pua ​​yttria. Peb kuj muab 3 mol feem pua ​​thiab 5 mol feem pua ​​yttria stabilized zirconia crucibles ntawm kev thov.
