Ububiko bwa Zirconiyani umweru, umuhondo cyangwa imvi iyo irimo umwanda, kandi muri rusange irimo HfO2, ntibyoroshye gutandukana. Hano hari ibintu bitatu bya kristu ya ZrO2 yera munsi yigitutu gisanzwe.
■Ubushyuhe buke monoclinic (m-ZrO2)■Ubushyuhe bwo hagati tetragonal (t-ZrO2)■Ubushyuhe bwo hejuru kubic (c-ZrO2)
Ubwoko butatu bwa kristaliste bubaho mubushyuhe butandukanye, kandi hariho umubano ukurikira wo guhinduka:
Ibiranga ceramika ya zirconi
High-gushonga-ingingo
Gushonga kwa Zirconiya ni: 2715 ℃, irashobora gukoreshwa nkibikoresho byo hejuru byubushyuhe
Gukomera cyane, kwihanganira kwambara neza
Ukurikije ubukana bwa Mohs: safiro>Ububiko bwa Zirconiya> Corning Glass> Aluminium magnesium alloy> Ikirahure gikonje> polyakarubone
Imbaraga nyinshi no gukomera
Imbaraga za zirconi zirashobora kugera: 1500MPa
Ubushyuhe buke bwumuriro hamwe na coefficient yo kwaguka
Mubikoresho bisanzwe bya ceramic, ubushyuhe bwumuriro niwo hasi cyane (1.6-2.03W / (mk)), kandi coefficient yo kwagura ubushyuhe yegereye icyuma.
Imikorere myiza y'amashanyarazi
Dielectric ihoraho ya zirconi ikubye inshuro 3 za safiro, kandi ibimenyetso birakomeye.
Gukoresha ceramika ya zirconi
Ububiko bwa Zirconiyazikoreshwa cyane muri 3C electronics, itumanaho rya optique, kwambara neza, biomedical, imitako, ubuzima bwa buri munsi, ibikoresho byo kwangara nibindi bice.
Ubuhanga bwo gutegura ibicuruzwa bya Zirconiya
Gucumura ninzira yingenzi cyane mugutegurazirconia ceramics, ubwiza bwo gucumura buzagira ingaruka muburyo butaziguye bwo gutunganya ceramic, gusa ubushyuhe bwo gucumura bwahinduwe neza, umubiri w urusoro uzaba utunganye. Gucumura bidafite ingufu nuburyo bukoreshwa cyane bwo gucumura.
Kuberako ibikoresho bya ceramique byera rimwe na rimwe bigoye gucumura, mugihe cyimikorere yimikorere, bimwe mubyongewemo ibicumuro mubisanzwe bitangizwa kugirango bibe igice cyo hasi cyo gushonga cyumuti ukomeye, icyiciro cyikirahure cyangwa ikindi cyiciro cyamazi, kugirango biteze imbere uduce duto nuduce twinshi. , kugirango ubone ibicuruzwa byuzuye, ariko kandi ugabanye ubushyuhe bwo gucumura.
Kugabanya ingano yifu ishoboka nimwe murwego rwingenzi rwo guteza imbere gucumura. Kuberako ifu nziza, imbaraga nyinshi zo hejuru, niko byoroshye gucumura. Kubikoresho bya ceramic nibicuruzwa bifite ibisabwa bisanzwe, gucumura bitari igitutu nuburyo bworoshye bwo gucumura.
