Zirconia Ceramics Kuedza

Wonder Garden Zirconia ceramic centre-post cartridges uye inotungamira mukwikwidzi wesimbi centre-post cartridges yakapihwa neWonder Garden kuti iongororwe.Kudzidza kusimba uye kuderera kwekupisa kwemasamples, Aliovalents Material Research yakashandiswa pycnometry, x-ray diffraction, scanning electron microscopy uye simba dispersive spectroscopy pamasampuli anosiyana kubva pristine kusvika pakuderedzwa (300 °C uye 600 °C). kureba uchishandisa yakaderera-speed wafering diamond saw (Allied HighTech, US) pa 200 rpm kuti ive nechokwadi chepamusoro chepamusoro chikamu chemuchinjikwa chinowanikwa.Zvadaro sampuli dzakashambidzwa mumvura yakasvibiswa mu ultrasonic cleaner, ndokuzocheneswa ne isopropanol uye DIW kekupedzisira.Samples dzakazoiswa mu2 muffle furnaces ndokuchengetwa pa300℃ uye 600℃ mumhepo (~Nitrogen 78%, Oxygen 21%, vamwe 1%).

Iyo yakajairika tembiricha yekushandisa yezvishandiso izvi kazhinji iri pa250 °C kusvika 350 °C, ine tembiricha yekushanda yakakura kubva pa450 °C kusvika 500 °C.Naizvozvo, tichifunga nezve kuchengetedza chinhu che1.2, izvi zvakakonzera kuongororwa kwezvinhu pa600 ° C.Maitiro ekuita maitiro akaitwa pane pristine, 300 °C uye 600 °C ye ceramic uye simbi yepakati-mbiru.

Density yakayerwa pachishandiswa gravimetric buoyancy method.X-ray diffraction (XRD) maitiro akawanikwa.Crystal domain size yakafungidzirwa kushandisa Scherrer equation kubva kuXRD diffraction peaks uchishandisa hupamhi hwakazara pahafu yepamusoro (FWHM) ye (111) peaks.Cross-sectional scanning electron microscopy (SEM) yakaitwa pane yakakwira vacuum kuti iwane yepamusoro resolution microstructure mifananidzo.Energy-Dispersive Spectroscopy (SEM/EDS) yakaitirwa kuongororwa kwekutanga kwemasampuli kuti iongororwe kana imwe shanduko yekuumbwa yakaitika pamusoro petembiricha yakataurwa.
