[email protected]Jul 31 2019 · But above all the key difference between zirconia and aluminum oxide is that zirconia occurs in a monoclinic crystal structure while aluminum oxide is in the trigonal crystal structure Moreover zirconia is slightly basic because it reacts slowly with strong acids such as HF and sulfuric acid however aluminum oxide is amphoteric and it can react with both acids and bases to form a
On the other hand Yttrium oxide widely used as stabilizer for Zirconia is a rare earth element with limited source However it is the cost for shaping zirconia that contributes the major part Density of zirconia is much higher than alumina and wear resistance of zirconia is far better than alumina
To evaluate zirconium oxide wear resistance in a ceramicceramic coupling a “ring on disk test” was performed The results medium print deepness 16 mm 3 h for zirconium oxide vs 00033 mm 3 h for alumina oxide make the zirconium oxide unsuitable for the use in clinical application as ceramicceramic coupling surface
