Abstract: A casting insert includes a casting insert wall formed substantially of a liquid-phase-sintered refractory metal alloy, a cavity formed by the casting insert wall, and at least one cooling duct, which is different from the cavity and which is formed at least partly within the cavity and/or which is formed at least partly within the casting insert wall. The casting insert wall has a wall thickness which can be defined as a normal distance between a point of the casting insert wall which faces the cavity and a point on an outer surface of the casting insert wall. The wall thickness is, at least in sections, less than 25% of a diameter of the casting insert.

Abstract: A ceramic holding element for a high-temperature furnace includes at least one fastening portion formed on a part of the holding element surface for mechanically connecting the holding element to a supporting structure. At least one heat conductor receiving portion on a part of the holding element surface receives a heat conductor. At least one groove is formed on a peripheral part of the surface of the holding element between the fastening portion and the heat conductor receiving portion. The groove extends substantially over the entire periphery of the peripheral part and at least one imaginary path between the fastening portion and the heat conductor receiving portion along the holding element surface crosses the groove. The groove has an aspect ratio, formed by a depth to width ratio of the groove, being greater than or equal to 1.5.
