Application of the solution–melt method for obtaining composite materials consisting of a metal matrix and CrSi$_2$ microcrystals

The possibility of obtaining composite materials in which the metal matrix is filled with CrSi$_2$ needle microcrystals is considered. It is shown that it is possible in principle to obtain a regular structure of CrSi$_2$ microcrystals in metal matrices of tin, aluminum, and their alloys. During chemical etching, a part of the matrix volume is dissolved, releasing “rods” of the semiconducting material. The thermoelectric parameters of such a system are estimated on the basis of the measured physical properties.
