Abstract
In its most general embodiment, the invention comprises an element made of at least one refractory ceramic material, with at least one channel which extends within the element, wherein the channel is at least partially formed by a number of discrete bodies in a ring or in the form of a sleeve, which are arranged one after the other in the longitudinal direction of the channel, and each body consists of a refractory ceramic material which is different from the circumferentially neighbouring refractory ceramic material of the element.
