Abstract: The invention relates to a sliding bearing material with a matrix material which consists of 0.5-5 wt. % nickel, 0.25-2.5 wt. % silicon, <0.1 wt. % lead, impurities that result from the metallurgical smelting process, and the rest being copper, with optionally at least one hard material and optionally at least one solid lubricant, and which has at least one tellurium additive. The invention also relates to a sliding bearing composite material which has a carrier layer, a bearing metal layer and a sliding layer applied to said bearing metal layer, the bearing metal layer consisting of such a sliding bearing material, as well as to a sliding element or sliding bearing that consists of such a sliding bearing composite material.

Abstract: This invention relates to a sliding bearing material with a matrix material which consists of 2.1-2.6 wt. % iron, 0.05-0.2 wt % zinc, 0.015-0.15 wt. % phosphorus, ?0.03 wt. % lead, ?0.2 wt. % impurities that result from the metallurgical melting process, and the rest being copper, with optionally at least one hard material and optionally at least one solid lubricant, and which has at least one additive selected from the group of tellurium, sulphur, chromium and zirconium. The invention also relates to a sliding bearing composite material with a backing layer, a bearing metal layer and a sliding layer applied to said bearing metal layer, the bearing metal layer consisting of such a sliding bearing material, as well as to a sliding element or sliding bearing that consists of such a sliding bearing composite material.

Abstract: The invention relates to a ceramic composite, in particular for use in secondary metallurgy, consisting of at least a first layer comprised of a carbon-containing, oxide refractory material, and a second layer comprised of a carbonless oxide refractory material bound with a binding agent.
