The presenter “ IBRAHIM MAJEED JASIM ” demonstrates the most important objectives of study : Preparation of three compounds of thermoelectric materials from Zintl-phase antimonite compounds  Eu_1-xYb_x Zn₂Sb₂ , YbZn_2-x Cd_xSb₂ & YbZn_2-x Mn_xSb₂ of short time 10-25min by Solid State Microwave Synthesis and study thermoelectric properties . This study prove that the compounds  Eu_0.6Yb_0.4Zn₂Sb₂ , YbCd₁.₆Zn_0.4Sb₂ &  YbZn_1.6Mn_0.4Sb₂  have the hexagonal crystal structure and it are promising thermoelectric materials.
