Gwajin Ceramics Zirconia

Al'ajabi Lambun Zirconia yumbu cibiyar-post harsashi da kuma babban mai gasa karfe cibiyar-post harsashi aka bayar da Wonder Garden domin bincike.Don nazarin dorewa da lalatawar thermal na samfuran, Aliovalents Material Research yi amfani da pycnometry, x-ray diffraction, scanning microscopy da makamashi dispersive spectroscopy akan samfuran da suka bambanta daga pristine zuwa ƙasƙanci (300 ° C da 600 ° C) samfuran an raba su ta hanyar. tsayin ta amfani da ma'aunin lu'u-lu'u mai ƙarancin saurin wafering (Allied HighTech, US) a 200 rpm don tabbatar da mafi girman sashin giciye.Sa'an nan kuma an wanke samfurori a cikin ruwa mai tsabta a cikin mai tsabta na ultrasonic, sa'an nan kuma an wanke shi da isopropanol da DIW na ƙarshe.Sa'an nan an sanya samfurori a cikin murhu 2 kuma an ajiye su a 300 ℃ da 600 ℃ a cikin iska (~ Nitrogen 78%, Oxygen 21%, wasu 1%).

Matsakaicin zafin jiki na waɗannan na'urori gabaɗaya shine 250 ° C zuwa 350 ° C, tare da matsakaicin zafin aiki daga 450 ° C zuwa 500 ° C.Sabili da haka, la'akari da yanayin tsaro na 1.2, wannan ya haifar da kimantawa na kayan a 600 ° C.An aiwatar da hanyoyin ƙira akan pristine, 300 ° C da 600 ° C don tukwane na yumbu da ƙarfe.

An auna girman ta ta hanyar amfani da hanyar buoyancy gravimetric.An sami nau'ikan ɓarna na X-ray (XRD).An kiyasta girman yankin Crystal ta amfani da ma'auni na Scherrer daga kololuwar rarrabuwar XRD ta amfani da cikakken nisa a rabin matsakaicin (FWHM) na kololuwar (111).An gudanar da sikanin sikanin sikanin ƙetare-ɓangarorin lantarki (SEM) a babban ɗigon ruwa don samun mafi girman ƙudurin hotuna.Energy- Dispersive Spectroscopy (SEM/EDS) an yi don bincike na farko na samfuran don bincika idan ƙarin canje-canjen haɗin gwiwa ya faru a sama da yanayin zafi da aka ambata.
