Results indicate that thesamples are comprised of slate-like grains growing up in different directions, and that grain size and pore play a domain role in electrical conductivity and thermal conductivity besides Seebeck coefficient.

• 结果显示烧结样品由不同取向的片状颗粒组成，颗粒大小以及颗粒间的气孔数量对样品的电导率和热导率有显著影响，对Seebeck系数影响不大。
