Teko ea Zirconia Ceramics

Wonder Garden Zirconia ceramic center-post cartridges le li-cartridges tsa tšepe tse ka sehloohong tsa setsi sa tšepe li fanoe ke Wonder Garden bakeng sa lipatlisiso.Ho ithuta ho tšoarella le ho senyeha ha mocheso oa lisampole, Aliovalents Material Research e sebelisitse pycnometry, x-ray diffraction, scanning electron microscopy le energy dispersive spectroscopy ho lisampole tse fapaneng ho tloha ho pristine ho ea ho tse senyehileng (300 °C le 600 °C). bolelele ba ho sebelisa sakha ea taemane e nang le lebelo le tlase (Allied HighTech, US) ho 200 rpm ho netefatsa hore karolo ea sefapano sa boleng bo holimo e fihletsoe.Ebe lisampole li ne li hlatsuoa ka metsi a deionized ka ultrasonic cleaner, ebe li hlatsuoa ka isopropanol le DIW ka lekhetlo la ho qetela.Ka mor'a moo, lisampole li ile tsa kenngoa ka har'a libono tse 2 tsa muffle 'me tsa bolokoa ho 300 ℃ le 600 ℃ moeeng (~Nitrogen 78%, Oxygen 21%, ba bang 1%).

Thempereichara e tloaelehileng ea ts'ebetso ea lisebelisoa tsena ka kakaretso e ho 250 °C ho ea ho 350 °C, ka mocheso o phahameng oa ts'ebetso ho tloha ho 450 °C ho isa ho 500 °C.Ka hona, ha ho nahanoa ka ntlha ea polokeho ea 1.2, sena se ile sa fella ka tlhahlobo ea thepa ho 600 ° C.Mekhoa ea ho khetholla litlhaku e ne e etsoa ka pristine, 300 °C le 600 °C bakeng sa liphatlalatso tsa setsi sa ceramic le tšepe.

Tekanyo e ile ea lekanngoa ho sebelisoa mokhoa oa gravimetric buoyancy.Ho ile ha fumanoa mekhoa ea X-ray diffraction (XRD).Boholo ba Crystal domain bo ne bo hakanngoa ho sebelisoa Scherrer equation ho tloha XRD diffraction litlhōrō ho sebelisa bophara bo feletseng ho halofo ea boholo (FWHM) ea litlhōrō tsa (111).Cross-sectional scanning electron microscopy (SEM) e entsoe ka vacuum e phahameng ho fumana litšoantšo tse phahameng ka ho fetisisa tsa sebopeho sa microstructure.Energy-Dispersive Spectroscopy (SEM/EDS) e ile ea etsoa bakeng sa tlhahlobo ea mantlha ea lisampole ho etsa lipatlisiso haeba liphetoho tse ling tsa sebopeho li etsahetse kaholimo ho mocheso o boletsoeng.
