I-Yttrium(yttrium oxide,Y2O3)i-zirconia ezinzile(zirconium dioxide,ZrO2)imidiya yokugaya inokuminyana okuphezulu, ama-super hardnes kanye nokuqina okuhle kokuphuka, okuvumela ukufeza ukusebenza kahle kokugaya okuphakeme uma kuqhathaniswa nezinye imidiya ye-conventioanl low density.I-UrbanMines igxile ekukhiqizeniI-Yttrium Stabilized Zirconia (YSZ) Ukugaya UbuhlaluImidiya enokuminyana okuphezulu kakhulu okungaba khona kanye namasayizi amancane okusanhlamvu aphakathi nendawo ukuze asetshenziswe ku-semiconductor, imidiya yokugaya, njll.
