zirconium vs alumina ceramic ring in finland

  • Alumina Vs Zirconium Oxide: A Comparative Wear

    To evaluate zirconium oxide wear resistance in a ceramic-ceramic coupling, a “ring on disk test” was performed. The results (medium print deepness: 16 mm 3 /h for zirconium oxide vs 0.0033 mm 3 /h for alumina oxide) make the zirconium oxide unsuitable for the use in clinical application as ceramic-ceramic coupling surface.

  • What's the differences between alumina and zirconia?

    2021-5-25 · Price: alumina vs zirconia. The most significant difference between these two materials is the price. Cost for zirconia is more than doubled for even the best alumina material. One of the reasons is the cost of the raw material. Compared with Zr, Al is far more abundant in the crust and it’s much cheaper.
