Optimization of Hot-Press Conditions of Zn4Sb3 for High Thermoelectric PerforPart 2. Mechanical Properties. — The title compound is hot-pressed at four
17- 008 mance.
different temperatures between 738 and 753 K and characterized by measurements of
Young's modulus, Vickers hardness, bending strength, and fracture toughness. Young's
modulus and Vickers hardness exhibit a linear correlation with hot-pressing temperature, while bending strength and fracture toughness show degradation upon high-temperature sintering at 753 K. The optimal sintering temperature is found to be 748 K.
