At least one part is formed of a refractory metal or a refractory metal alloy. The container makes it possible to provide great variety, both with regard to form and dimensions of the container, which is impermeable to ceramic melts even under high operating temperatures. A method for producing a container is also provided.

Abstract: A process for producing a layer or a body built up of layers. A process gas which has a pressure of >10 bar is accelerated in a convergent-divergent nozzle and a coating material which is formed by particles and is composed of Mo, W, an Mo-based alloy or a W-based alloy is injected into the process gas. The particles are at least partly present as aggregates and/or agglomerates. It is possible to produce dense layers and components in this way. We also describe layers and components having a microstructure with cold-deformed grains having a high aspect ratio.
