I-Zirconia eqinile ye-Yttria

Incazelo

I-Yttria ezinzile i-Zirconia Y-TZP, ZrO₂+Y₂O₃, iyimpahla yobumba engenabuthi, engenaphunga.ZrO₂i-crystal ye-monoclinic ekamelweni lokushisa, izinga lokushisa lokuguqulwa kwesigaba se-Zirconia liyashintshwa ukuze likhiqize amakristalu azinzile we-cubic kanye ne-tetragonal ekamelweni lokushisa ngokungeza i-Yttria.Eyaziwa ngele-“ceramic steel”, i-Yttria-stabilized Zirconia ivamise ukulungiswa ngokucindezela okushisayo, ukucindezela okomile nokucindezela kwe-isostatic sintering.Njengomshini wayo wokuqinisa ukuguqulwa kwesigaba, i-Yttria ezinzile i-tetragonal Zirconia crystal ceramic inezakhiwo ezinhle kakhulu zomshini ezifana namandla aphezulu, ukuqina kokuphuka okuphezulu, amandla okugoba okuphezulu, ukumelana komthelela wemishini kanye nokumelana nokugqoka okuphezulu ekamelweni lokushisa, ukuqhutshwa kwe-ionic okuphezulu, kanye nokumelana nokugqwala kwamakhemikhali okuhle kakhulu. , ukuzinza okuhle ku-asidi, i-alkali, ingilazi nensimbi encibilikisiwe ngaphandle kwe-sulfuric acid ne-hydrofluoric acid.I-Yttria-stabilised Zirconia Y-TZP e-Western Minmetals (SC) Corporation ingalethwa ngenani lokuqamba le-ZrO₂86% + Y₂O₃I-14% ngosayizi we-powder noma izingxenye ze-ceramic njengemidwebo yamakhasimende enephakheji ye-10-20kgs esikhwameni sokhuni.

Izinhlelo zokusebenza

Ngosayizi wezinhlayiyana zekristalu ecwebe kakhulu, ukufana kwezinhlayiyana kanye nesilinganiso sokwakheka esinengqondo, i-Yttrium ezinzile i-Zirconia Y-TZP isiphenduke into eyinhloko yokukhiqiza izinzwa zomoya-mpilo, amaseli kaphethiloli aqinile, izinga lokushisa eliphezulu, izitsha zobumba ze-piezoelectric, izitsha zobumba ze-ferroelectric, amaphampu omoya-mpilo, amathuluzi okusika. futhi njenge-ceramic yesakhiwo, i-ceramic ferrule kanye nomkhono, izinto zobumba zikagesi, izinto eziphikisayo ezinkulu, amadivaysi okuxhumana abonakalayo nebhethri likaphethiloli we-oxygen njll.
