Brief description

Molten salts are becoming increasingly important as a material for heat transfer and storage. Molten salts are particularly characterised by their low vapour pressure at high temperatures and low costs. However, the challenges lie precisely in the technical realisation of this technology, since high demands are placed on the materials used due to high temperatures and corrosiveness.

The requirements for components to be used in liquid salt plants are very complex and result in particular from the combination of thermal and corrosive stress. In the one-year project, research is to be carried out to find out which materials meet these requirements in order to derive possible construction materials for the construction of pumps.

In a second part of the project, the conditions for experimental investigations will be conceptualised to prove the suitability of the selected materials for use as pump components.

The aim of the work is to elaborate a detailed test programme, which includes both static and dynamic corrosion tests and can be used as a basis for the use of a test of a model-pump in chloride salt at 800 °C.
