Solid-phase synthesis of some transition metal silicides

Role of milling parameters and impurity on the thermoelectric properties of mechanically alloyed chromium silicide

“…Mechanochemical synthesis of CrSi 2 is reported in literature [7,8], but one of its major drawbacks is the contamination arising during the milling process. The transport and thermal properties of arc melted CrSi 2+x have been shown to change drastically depending on the silicon stoichiometry and secondary phases present [9,10] value peaks around x = −0.01 before degrading due to the high conductivity of CrSi phase.…”

Thermoelectric properties and stability of nanostructured chromium disilicide CrSi2

“…Up to now, the maximum ZT value of pure CrSi 2 is 0.25 at 900 K in single crystal along the c-axis. 13,14 A better understanding of the phonon scattering mechanisms is the first step of a research path to decrease the lattice component of the thermal conductivity of CrSi 2 , an indispensable action before its use in thermoelectric applications.…”
