Key Points

• To synthesize and characterize thermoelectric Mg2Si using self-propagating high-temperature synthesis.
• Utilized self-propagating high-temperature synthesis for preparation.
• Characterized Mg2Si using X-ray diffraction (XRD) and scanning electron microscopy (SEM).
• Measured product density, porosity, electrical resistivity, and Seebeck coefficient.
• Electrical resistivity displayed a nonlinear, semiconductor-like behavior.
• Seebeck coefficient followed a nonlinear curve, recording a minimum of –367 µV/K at 589 K.
