In the paper by K. Rajput and S. Vitta published in
the present journal the synthesis and the thermoelectric
properties of the dysprosiumcontaining clathrate Dy8Al16Si30
were reported. We prepared two samples following exactly to
the technique described in the paper.OurXRDandSEM/EDX
investigations do not confirm the presence of any amount of a
Dy-containing clathrate phase in the sample.
