Ubuhlalu be-Zirconium oxide, obaziwa nangokuthi ubuhlalu be-zirconia, yizinhlayiya ezincane eziyindilinga ezenziwe ngokuyinhloko nge-zirconium oxide (ZrO2).I-Zirconium oxide iyimpahla ye-ceramic eyaziwa ngobulukhuni bayo obukhulu, ukumelana nokugqoka, nokuzinza kokushisa.Lobu buhlalu buthola ukusetshenziswa okuhlukahlukene kuzo zonke izimboni ezahlukahlukene, ikakhulukazi ekucubunguleni izinto zokwakha, amakhemikhali, nezinkambu ze-biomedical.
