Zirconia Ceramics Experimental

Wonder Garden Zirconia ceramic iziko-post iikhatriji kunye okhuphisana ophambili metal iziko-post iikhatriji zibonelelwe yi Wonder Garden uphando.Ukuphonononga ukuqina kunye nokuthotywa kwe-thermal yeesampulu, i-Aliovalents Material Research isetyenziselwe i-pycnometry, i-x-ray diffraction, i-electron microscopy yokuskena kunye ne-energy dispersive spectroscopy kwiisampulu ezohlukeneyo ukusuka kwi-pristine ukuya kokwehla (300 °C kunye ne-600 °C). ubude kusetyenziswa isarha yedayimani enesantya esisezantsi (Allied HighTech, US) kwi-200 rpm ukuze kuqinisekiswe ukuba elona candelo liphezulu lomnqamlezo liphunyeziwe.Emva koko iisampuli zahlanjululwa emanzini adibeneyo kwi-ultrasonic cleaner, emva koko ihlanjululwe nge-isopropanol kunye ne-DIW okokugqibela.Iisampulu zaye zafakwa kwii-muffle furnaces ezi-2 kwaye zigcinwe kwi-300℃ kunye ne-600℃ emoyeni (~Nitrogen 78%, i-Oxygen 21%, abanye i-1%).

Ubushushu obuqhelekileyo bokusebenza kwezi zixhobo ngokuqhelekileyo bukuma-250 °C ukuya kuma-350 °C, nobona bushushu bokusebenza buphezulu obusuka kuma-450 °C ukuya kuma-500 °C.Ngoko ke, ngokuqwalasela ukhuseleko lwe-1.2, oku kubangele ukuvavanywa kwezinto eziphathekayo kwi-600 °C.Iindlela zokulinganisa iimpawu zenziwa kwi-pristine, 300 °C kunye ne-600 °C kwi-ceramic kunye nezithuba zentsimbi.

Ubuninzi bulinganiswe kusetyenziswa indlela yegravimetric buoyancy.Iipateni ze-X-ray diffraction (XRD) zafunyanwa.Ubungakanani besizinda se-Crystal buqikelelwa kusetyenziswa i-equation ye-Scherrer ukusuka kwi-XRD diffraction peaks usebenzisa ububanzi obupheleleyo kwisiqingatha esiphezulu (FWHM) se-111).I-Cross-sectional scanning electron microscopy (SEM) yenziwa kwi-vacuum ephezulu ukuze ifumane eyona mifanekiso iphezulu ye-microstructure.I-Energy-Dispersive Spectroscopy (SEM/EDS) yenzelwe ukuhlalutya okusisiseko kweesampulu ukuphanda ukuba ngaba kukho utshintsho olongezelelekileyo lokwakheka okungaphezulu kwamaqondo obushushu akhankanyiweyo.
