Zirconiya (YSZ) Gusya amashanyarazi
Ugereranije n'inkoni ya alumina Yttria ituje zirconia (YSZ YTZP) inkoni yashoboraga kwihanganira ubushyuhe bwinshi.Zirconiya nayo ifite ruswa nziza no kwambara birwanya.Nkibikoresho byangiritse cyane, ubushyuhe bwakazi bwinkoni ya zirconi bushobora kuba hejuru ya 1900C kandi bigahinduka kumiti myinshi yangiza.Zirconia ibamba nayo itanga ubushyuhe buke cyane nubushyuhe bwamashanyarazi amking nibyiza kubisabwa bisaba amashanyarazi hamwe nubushyuhe.
Ariko, bitandukanye na nitride ya boron, inkoni ya Zirconia ntabwo isabwa gukoreshwa nkibikoresho fatizo kugirango imirimo ikorwe neza, kubera ubukana bwinshi no kwambara birwanya.
Yiho YSZ
Nkumuntu utanga ibikoresho byingenzi byabugenewe byabugenewe muburasirazuba bwa Amerika, QS Advanced Materials ikorana cyane nabakora uruganda rukora sinema nogukora imashini kugirango batange ibicuruzwa bya zirconi bihamye kandi bifite igiciro cyiza cyane.Dukomeje gutanga umusaraba wa zirconi nibindi bikoresho byibanze.Hamwe na kimwe cya kabiri kirangiye, hamwe nubushobozi buhanitse, inyungu mugihe cyo kuyobora nigiciro kiratangwa.
Porogaramu ya Yttria Ihamye Zirconiya (YSZ, YTZP) ibice
• Ikoreshwa mu gusya ibikoresho byubutaka, ibikoresho bya magneti hamwe nicyitegererezo
• Kwambara hamwe nibindi bikoresho byo gukanika
• Ibice bidasanzwe bya pompe
Imikorere ya Zirconiya

Gupakira
Nkibikoresho byubutaka, ibikoresho bya Zirconiya biracyavunika, nubwo YSZ hari uburyo bworoshye.Inkoni yacu ya zirconi isanzwe ifatwa mumifuka ya pulasitike na vacuum, kandi ikarinda ifuro riremereye.
