Hoʻokolohua Zirconia Ceramics

Na Wonder Garden Zirconia ceramic center-post cartridges a me nā pahu pahu metala waena o ka mea hoʻokūkū alakaʻi i hoʻolako ʻia e Wonder Garden no ka hoʻokolokolo ʻana.No ke aʻo ʻana i ka lōʻihi a me ka hoʻohaʻahaʻa wela o nā laʻana, ua hoʻohana ʻo Aliovalents Material Research i ka pycnometry, x-ray diffraction, scanning electron microscopy a me ka ikehu dispersive spectroscopy ma nā laʻana e ʻokoʻa ana mai ka maʻemaʻe a me ka degraded (300 °C a me 600 °C). ka lōʻihi e hoʻohana ana i ka ʻike daimana wafering haʻahaʻa (Allied HighTech, US) ma 200 rpm e hōʻoia i ka loaʻa ʻana o ka pauku keʻa kiʻekiʻe loa.A laila holoi ʻia nā laʻana i ka wai deionized i ka hoʻomaʻemaʻe ultrasonic, a laila holoi ʻia me ka isopropanol a me DIW no ka manawa hope loa.Hoʻokomo ʻia nā laʻana i loko o 2 mau umu muffle a mālama ʻia ma 300 ℃ a me 600 ℃ i ka ea (~ Nitrogen 78%, Oxygen 21%, nā mea ʻē aʻe 1%).

ʻO ka mahana hana maʻamau o kēia mau mea maʻamau ma 250 °C a 350 °C, me ka wela hana kiʻekiʻe loa mai 450 °C a 500 °C.No laila, e noʻonoʻo ana i kahi mea palekana o 1.2, ua hopena kēia i ka loiloi o ka mea ma 600 °C.Ua hana ʻia nā ʻano hana ma luna o ka maʻemaʻe, 300 °C a me 600 °C no nā pou kikowaena ceramic a me metala.

Ua ana ʻia ka mānoanoa me ka hoʻohana ʻana i ke ʻano gravimetric buoyancy.Ua loaʻa nā hiʻohiʻona X-ray diffraction (XRD).Ua manaʻo ʻia ka nui o ka waihona kristal me ka hoʻohana ʻana i ka hoʻohālikelike Scherrer mai nā piko ʻokoʻa XRD me ka hoʻohana ʻana i ka laulā piha ma ka hapalua kiʻekiʻe (FWHM) o nā piko (111).Ua hana 'ia ke 'ano o ka cross-sectional scanning electron microscopy (SEM) ma ka vacuum ki'eki'e no ka loa'a 'ana o nā ki'i microstructure ho'onā ki'eki'e loa.Ua hana ʻia ka Energy-Dispersive Spectroscopy (SEM/EDS) no ka nānā ʻana i nā mea hoʻohālike o nā laʻana e noiʻi inā loaʻa nā hoʻololi hou aʻe ma luna o nā mahana i ʻōlelo ʻia.
