Abstract

Mg₂Si was prepared via self-propagating high-temperature synthesis. Characterization by XRD and SEM confirmed Mg₂Si as a basis. The synthesized product density, porosity, electrical resistivity, and Seebeck coefficient were measured. Electrical resistivity showed a nonlinear, semiconductor-like dependence. Similarly, the Seebeck coefficient followed a nonlinear trend, reaching a minimum of –367 µV/K at 589 K.

热电Mg2Si的自传播高温合成

采用自蔓延高温合成法制备了Mg2Si。XRD和SEM表征证实了Mg2Si为基。测定了合成产物的密度、孔隙度、电阻率和塞贝克系数。电阻率表现出一种非线性的、类似半导体的依赖性。同样，塞贝克系数也呈非线性趋势，在589 K时达到最小值-367µV/K。

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
