  • the liquid metals mentioned in the cited work are aggressive and cause strong erosion phenomena on the walls and on thermal loading and unloading equipment. As will be described in the publication CN 1504716A, this erosion can be limited by limiting the operating temperature to below 620 0 C, but not completely prevented.
  • WO 79/01004 A1 describes a solar energy system with a collector for collecting and concentrating the solar radiation and a collector coupled to the receiver, which is to convert the radiation into thermal energy.

Filling one liquid aluminum at a temperature of 900 0 C, its state is represented by point 11 in Figure 1, in an iron crucible, then the resulting system is initially away from the thermodynamic equilibrium. In order to reach thermodynamic equilibrium, part of the solid wall material dissolves in the liquid aluminum and thus leads to erosion of the wall.
  • the binary system iron-aluminum has reached the state of thermodynamic equilibrium at a temperature of 900 0 C, when the melt consists of about 90 percent by mass of aluminum and about 10 percent by mass of iron. This condition is characterized by the point 12 in FIG. If such a condition is reached, it is called a solubility equilibrium. After reaching the solubility equilibrium, no further migration erosion takes place.

  • FIG. 22 A second example of preventing migration erosion by providing a solubility weight is shown in FIG. If a eutectic alloy of iron and silicon is heated starting from the solid state of matter identified as point 21 in FIG. 2 in the liquid state of aggregation designated as point 22
  • thermodynamic equilibrium a part of the solid wall material dissolves in the liquid melt and thus leads to the erosion of the wall.
  • the binary system iron-silicon which is also referred to as ferrosilicon, at a temperature of 1400 0 C has reached the marked in Figure 2 as point 23 state of thermodynamic equilibrium on the liquidus curve 24 when the melt to about 90 percent by mass of iron and to about 10 percent by mass silicon.

  • a high-temperature latent heat store can be produced if the liquid storage medium and the solid wall material are brought into a thermodynamic equilibrium, preferably a solubility equilibrium, in the case of maximum thermal loading, as a result of which further traveling erosion is prevented.
