Zirconia eriri bụ ụdị polycrystalline refractory eriri ihe.Njupụta ndị ikwu bụ 5.6 ~ 6.9.Ọ nwere ezigbo nkwụsi ike nke kemịkalụ na nguzogide oxidation, conductivity dị ala, mmetụta nguzogide, na sinterability.N'ihi na elu agbaze ebe, na-abụghị ọxịdashọn na ndị ọzọ elu okpomọkụ àgwà nke ZrO2, ZrO2 eriri nwere elu ọrụ okpomọkụ karịa ndị ọzọ refractory emep uta eri dị ka alumina eriri, mullite eriri, aluminum silicate eriri, wdg Zirconia eriri eji ogologo oge. na ultra-elu okpomọkụ oxidation ikuku n'elu 1500 ℃.Oke ojiji okpomọkụ bụ ruo 2200 ℃, na ọbụna na 2500 ℃, ọ ka nwere ike ịnọgide na-enwe a zuru ezu eriri udi, na nwere ike elu okpomọkụ chemical Njirimara, corrosion eguzogide, ọxịdashọn eguzogide, thermal ujo eguzogide, na-abụghị volatilization, na ọ dịghị mmetọ. .Ọ bụ ugbu a n'ụwa kacha elu refractory eriri ihe.
Ngwa
Zirconia gụnyere oxygen na zirconium.A na-ekewa ya na clinozoite na zircon.
Clinozoite bụ kristal monoclinic nwere ọcha na-acha odo odo.
Zircon bụ ịnweta miri emi nke nkume na-egbuke egbuke, na-acha odo odo, agba aja aja, akwụkwọ ndụ akwụkwọ ndụ na agba ndị ọzọ, ike ndọda nke 4.6-4.7, ike nke 7.5, ike siri ike na-egbuke egbuke, na enwere ike iji ya dị ka akụrụngwa maka seramiiki glaze.
