Beschreibung
Zusammenfassung:A powder of carbonaceous matrix particles with silicon-based sub-particles dispersed therein, wherein the particles have a harmonic mean value of their average Vickers hardness value and their average elastic modulus value, both values of hardness and elasticity being measured by nanoindentation and expressed in MPa, being superior or equal to 7000 MPa and inferior or equal to 20000 MPa.
