I-Zirconia (YSZ) imidiya yokugaya isilinda yesilinda
Uma kuqhathaniswa nezinduku ze-alumina ze-Yttria ezizinzile ze-zirconia (YSZ YTZP) zingamelana nezinga lokushisa eliphakeme nakakhulu.I-Zirconia nayo inokugqwala okungcono nokugqoka ukumelana.Njengempahla ephikisayo ngokwedlulele, izinga lokushisa elisebenzayo le-zirconia rods lingaba phezulu lifike ku-1900C futhi lizinze nakumakhemikhali amaningi agqwalayo.I-Zirconia crucibles iphinde inikeze ukuguquguquka okuphansi kakhulu kokushisa kanye nogesi okwenza kube yinto ekahle ekusetshenzisweni kudinga ukufakwa kukagesi nokushisa.
Kodwa-ke, ngokungafani ne-boron nitride, induku ye-Zirconia ayinconywa ukuthi isetshenziswe njengempahla eluhlaza ukuze kuqhutshekwe nomsebenzi womshini, ngenxa yokuqina okuphezulu nokugqoka ukumelana.
Yiho YSZ Izinduku
Njengomphakeli omkhulu wezinto zobumba ezenziwe ngokwezifiso ezithuthukisiwe ogwini olusempumalanga ye-USA, i-QS Advanced Materials isebenzisana eduze nabakhiqizi be-ceramic sintering namandla okwenza imishini ukuze banikeze imikhiqizo ye-zirconia ezinzile enenani elisebenza kahle kakhulu.Siqhubeka nokuhlinzeka nge-zirconia crucibles nezinye izinto eziyisisekelo.Ngamasheya aqedwe kancane, namandla okukhiqiza aphezulu, izinzuzo zesikhathi sokuhola nezindleko zinikeziwe.
Izicelo zezingxenye ze-Yttria Stabilized Zirconia (YSZ,YTZP).
• Isetshenziselwa ukugaya izinto zobumba zobumba, izinto zikazibuthe namasampula ezinto eziphilayo
• I-Bearing kanye nezinye izingxenye zemishini ezingagugi
• Izingxenye zephampu ezikhethekile

Ukupakisha
Njengempahla ye-ceramic, i-Zirconia material is still brittle, nakuba i-YSZ ngandlela-thile iguquguquka.Izinduku zethu ze-zirconia zivame ukubanjwa ezikhwameni zepulasitiki nge-vacuum, futhi zivikeleke ngegwebu elisindayo.
