Abstract (en)
[origin: WO2022112377A1] The invention relates to a plurality of particles having a coating, the particles consisting of a metal selected from the group consisting of copper, cobalt, ruthenium, nickel, palladium, iridium, platinum, an alloy based on one of said metals, and alloys based on a mixture of two or more of said metals, and the coating being a graphene-like coating, characterized in that, after being compressed into a test specimen, the thermal conductivity of the particles having the coating is ≥ the thermal conductivity of the same particles without the coating, and in that the abrasion rate is ≤ 15*10-4 mm3/N*m, preferably ≤ 5*10-4 mm3/N*m.
