Zirconai cov nplais qhwv tsev
Feb 26, 2018| Zirconia ceramic thaiv yog muab faib ua ob hom purity thiab zoo tib yam. High purity alumina ceramics nrog ntau tshaj 99.9% Al2O3 feem ntau yog ua los ntawm cov iav uas yaj los hloov lub platinum crucible vim tias lawv cov cua kub sintering yog li 1650-1990 ° C thiab lawv cov kab mob txuas wavelength ntawm 1-6 μm.
Kev siv nws lub teeb thiab alkali corrosion resistance yuav siv tau raws li sodium teeb; nyob rau hauv kev lag luam hauv tuam txhab hluav taws xob siv tau ua cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntau. Raws li qhov sib txawv Al2O3 cov ntsiab lus, alumina ceramic yog faib ua 99 plooj (porcelain), 90 plooj (porcelain), 90 plooj (veneers), 85 plooj (porcelain) thiab lwm yam, tej zaum Al2O3 cov ntsiab lus ntawm 80% los yog 75% kuj yog cais raws li cov kab npuas alumina.
Ib ntawm 99 alumina cov ntaub ntawv siv zas ua siv zus tau cov khoom kub, thawv rau roj hmab thiab cov khoom siv tshwj xeeb coj los tiv thaiv, xws li cov hlua khau, cov ntxhuav thiab cov dej qub, thiab lwm yam khoom; 95 alumina porcelain yog siv los ua corrosion-resistant, lub cev-resistant Cheebtsam; vim muaj kev sib txuas ntawm qee qhov kev sib txuas lus los ua kom cov hluav taws xob muaj zog thiab kev ua kom muaj zog, nrog molybdenum, niobium, tantalum thiab lwm yam hlau thaiv, thiab qee yam ua hluav taws xob nqus khoom.
