In the literature, there is not enough information concerning behavior of high-temperature phase change heat storage materials, undergone to repeated cycles of fusion and solidification. Below we will consider some works, in which this problem was studied.
However, rather low thermal capacity of sensible heat storage materials leads to considerable volumes heat storage units (HSU).
