Abstract The time and energy efficient synthesis of high performance β-Zn4Sb3 is essential for its thermoelectric (TE) based commercialization. In the present work, a facile yet scalable single-step processing has been demonstrated by employing reactive sintering at optimal conditions, to obtain dense polycrystalline p-type β-Zn4Sb3 bulk TE materials with a high TE figure-of-merit, ZT ~ 1 at 623 K. The reactive sintering at optimal sintering condition with high heating rates, enabled controlled tuning of the competing ZnSb system phases for attainment of superior TE performance in a reliable and a reproducible way. Thus, making significant contributions towards commercialization of β-Zn4Sb3 based TE devices.
