M′ is one or more elements of the group Al, B and Co. M″ is a dopant different from M and M′, and x, a, b and c are expressed in mol with −0.02≤x≤0.02, 0≤c≤0.05, 0.10≤(a+b)≤0.65 and 0≤z≤0.05. The material has an unconstrained cumulative volume particle size distribution value (Γ(D10)), a cumulative volume particle size distribution value after having been pressed at a pressure of 200 MPa (Γ(D10)) and a cumulative volume particle size distribution value after having been pressed at a pressure of 300 MPa (Γ(D10)). When Γ(D10) is compared to Γ(D10), the relative increase in value is less than 100%. When Γ(D10) is compared to Γ(D10), the relative increase in value is less than 120%.",
