I-Zirconia Ceramics Experimental

I-Wonder Garden Zirconia Ceramic center-post cartridges kanye ne-metal center-post cartridges eqhudelana naye kuhlinzekwe yi-Wonder Garden ukuze kuphenywe.Ukuze kutadishwe ukuqina nokuwohloka kokushisa kwamasampuli, i-Aliovalents Material Research isebenzise i-pycnometry, i-x-ray diffraction, i-electron microscopy yokuskena kanye ne-energy dispersive spectroscopy kumasampuli ahluka ukusuka kokucwebile kuye kowonakele (300 °C no-600 °C). ubude kusetshenziswa isaha ledayimane eliphekwe ngesivinini esiphansi (i-Allied HighTech, e-US) ku-200 rpm ukuze kuqinisekiswe ukuthi isigaba esiphezulu sekhwalithi esiphezulu siyafinyelelwa.Khona-ke amasampula ahlanjululwa emanzini angcolile ku-ultrasonic cleaner, bese ehlanjululwa nge-isopropanol ne-DIW okokugcina.Amasampuli abese efakwa ezithandweni ze-muffle ezi-2 futhi agcinwe ku-300 ℃ kanye no-600 ℃ emoyeni (~Nitrogen 78%, i-Oxygen 21%, abanye 1%).

Izinga lokushisa elijwayelekile lokusebenza lalezi zisetshenziswa ngokuvamile liba ku-250 °C kuya ku-350 °C, nezinga lokushisa eliphezulu lokusebenza elisuka ku-450 °C ukuya ku-500 °C.Ngakho-ke, uma kucatshangelwa isici sokuphepha esingu-1.2, lokhu kuholele ekuhlolweni kwezinto ezibonakalayo ku-600 °C.Izindlela zokuhlukanisa izinhlamvu zenziwa endaweni ehlanzekile, engu-300 °C no-600 °C ezinsikeni ze-ceramic nezensimbi.

Ukuminyana kukalwe kusetshenziswa indlela ye-gravimetric buoyancy.Kutholwe amaphethini e-X-ray diffraction (XRD).Usayizi wesizinda se-Crystal ulinganiselwe kusetshenziswa i-equation ye-Scherrer kusuka eziqongweni ze-XRD diffraction kusetshenziswa ububanzi obugcwele kuhhafu esiphezulu (FWHM) yeziqongo ze-(111).I-Cross-sectional scanning electron microscopy (SEM) yenziwe endaweni engenalutho ephezulu ukuze kutholwe izithombe ze-microstructure ezinesinqumo esiphezulu.I-Energy-Dispersive Spectroscopy (SEM/EDS) yenziwe ukuze kuhlaziywe amasampula ukuze kuphenywe uma izinguquko zokuqamba zenzeke ngaphezu kwamazinga okushisa ashiwo.
