  • Opaque red polycrystalline ceramic
    Patent number: 10611692
    Abstract: A polycrystalline ceramic solely formed based on alumina, on chromium oxide and on magnesium oxide, where the polycrystalline ceramic contains between 0.8% and 1.2% of chromium oxide by total weight of the polycrystalline ceramic and between 0.03% and 0.09% of magnesium oxide by total weight of the polycrystalline ceramic, making it possible to obtain a red ceramic with a toughness (Kc) at least equal to 2.8 MPa·m1/2.
