[Objective]Alloying methods were explored for PbTe thermoelectric materials.[Methods]High energy mechanical ball milling method and high frequency melting method were used to prepare PbTe thermoelectric materials.Firstly,the fractions of the samples and the milling time were adjusted to obtain the high quality samples.Secondly,the high frequency melting method was used to prepare the PbTe samples.Finally,the X-ray diffraction(XRD)and scanning electron microscope(SEM)were employed to obtain the crystal infor...
