Zirconia qws Description
Zirconia yog ib qho oxide uas muaj lub zog tensile siab, siab hardness thiab corrosion kuj. Nws tsis pom zoo li cov oxide ntshiab hauv qhov xwm txheej. Lub ntsiab qhov chaw ntawm zirconium yog zirconate (ZrO2-SiO2, ZrSiO4) thiab baddeleyite (ZrO2), thiab feem ntau ntawm cov khoom siv yog chemically muab rho tawm los ntawm ob minerals.
Cov oxides sib txawv, xws li yttrium oxide (Y2O3), calcium oxide (CaO) lossis magnesium oxide (MgO), tuaj yeem muab ntxiv rau zirconia kom ruaj khov, tso cai rau daim ntawv tetragonal nyob rau hauv chav tsev kub tom qab sintering. Qhov sib ntxiv ntawm qhov sib txawv ntawm cov stabilizers tso cai rau tsim ib feem los yog tag nrho stabilized zirconia uas, thaum ua ke nrog cov kev hloov hauv cov txheej txheem, tej zaum yuav ua rau ceramics nrog tshwj xeeb cov khoom xws li siab flexural zog thiab tawg toughness, siab hardness, zoo heev tshuaj tiv thaiv thiab zoo conductivity. ions. Lub zirconia tag nrho ruaj khov yog tau los ntawm kev ntxiv cov nyiaj stabilizing oxides txaus, xws li 16mol feem pua magnesia (MgO), 16mol feem pua ntawm limestone (CaO) lossis 8 mol feem pua yttria (Y2O3). Txij li thaum ib feem stabilization ntawm zirconia yog tau nrog tib oxides, tab sis nyob rau hauv me me npaum li cas (xws li 2 mol feem pua rau 3mol feem pua yttria), ib tug multiphase qauv yog tsim, uas feem ntau muaj tetragonal thiab cubic zirconia feem ntau / monoclinic precipitated nyob rau hauv me me. Kev hloov pauv ntawm tetragonal zirconia rau hauv monoclinic yog qhov tshwm sim los ntawm qhov kub thiab txias, vapor, qhov loj me, micro-thiab macrostructure ntawm cov khoom, thiab kuj los ntawm cov concentration ntawm stabilizing oxides. Qhov loj me me rau cov zirconia ib nrab stabilized yuav tsum tau khaws cia rau hauv daim ntawv tetragonal ntawm chav tsev kub yog {{10}}.2µm txog 1μm (rau kev sib xyaw ntawm 2 feem pua rau 3 mol feem pua yttria), vim tias, Hauv qab 0.2 micrometers, kev hloov pauv mus rau theem monoclinic tsis tuaj yeem ua tau.
