Zirconia Ceramics Experimental

Wonder Garden Zirconia ceramic center-post cartridges ndi ma cartridge achitsulo otsogola omwe amapikisana nawo adaperekedwa ndi Wonder Garden kuti afufuze.Kuti aphunzire kulimba ndi kuwonongeka kwa kutentha kwa zitsanzozo, Aliovalents Material Research adagwiritsa ntchito pycnometry, x-ray diffraction, scanning electron microscopy ndi mphamvu dispersive spectroscopy pa zitsanzo zosiyanasiyana pristine kuonongeka (300 °C ndi 600 °C). kutalika ntchito otsika-liwiro wopatulira macheka diamondi (Allied HighTech, US) pa 200 rpm kuonetsetsa apamwamba kwambiri mtanda gawo zimatheka.Ndiye zitsanzo anatsuka mu deionized madzi mu akupanga zotsukira, ndiye rinsed ndi isopropanol ndi DIW kwa nthawi yotsiriza.Zitsanzo zidayikidwa mu ng'anjo ziwiri za muffle ndikusungidwa pa 300 ℃ ndi 600 ℃ mumlengalenga (~ Nitrogen 78%, Oxygen 21%, ena 1%).

Kutentha kwapang'onopang'ono kwa zida izi nthawi zambiri kumakhala 250 °C mpaka 350 °C, komwe kumakhala kutentha kwambiri koyambira 450 °C mpaka 500 °C.Chifukwa chake, poganizira chitetezo cha 1.2, izi zidapangitsa kuwunika kwa zinthuzo pa 600 ° C.Njira zopangira zilembo zidachitika pa pristine, 300 °C ndi 600 °C pazitsulo za ceramic ndi zitsulo zapakati.

Kachulukidweko adayesedwa pogwiritsa ntchito njira ya gravimetric buoyancy.Zithunzi za X-ray diffraction (XRD) zinapezedwa.Kukula kwa Crystal domain kuyerekezedwa pogwiritsa ntchito Scherrer equation kuchokera ku XRD diffraction nsonga pogwiritsa ntchito m'lifupi mwake pa theka lapamwamba (FWHM) la nsonga za (111).Cross-sectional scanning electron microscopy (SEM) idachitidwa pa vacuum yapamwamba kwambiri kuti apeze zithunzi zapamwamba kwambiri za microstructure.Energy-Dispersive Spectroscopy (SEM/EDS) idapangidwa kuti iwunikenso zitsanzo kuti zifufuze ngati kusintha kwina kwapangidwe kunachitika pamwamba pa kutentha komwe kwatchulidwa.
