KUPFER-KERAMIK-VERBUND
The invention relates to a copper-ceramic composite, comprising a ceramic substrate, which contains aluminum oxide, a coating on the ceramic substrate made of copper or a copper alloy, wherein the aluminum oxide has an average grain form factor Ra(Al2O3), determined as an arithmetic average value from the form factors of the grains of the aluminum oxide, the copper or the copper alloy has an average grain form factor Ra(Cu), determined as an arithmetic average of the form factors of the grains of the copper or copper alloy, and the average grain form factors of the aluminum oxide and copper or copper alloy meet the following condition: 0.5≤Ra(Al2O3)/Ra(Cu)≤2.0.
