Mg3Sb2-based thermoelectric material with good thermal stability and preparation method thereof
The invention provides an Mg3Sb2-based thermoelectric material with good thermal stability and a preparation method thereof, and belongs to the technical field of thermoelectric materials. The invention provides an Mg3Sb2-based thermoelectric material with good thermal stability. The Mg3Sb2-based thermoelectric material comprises an Mg3Sb2 base material and an MgO protective layer deposited on the surface of the Mg3Sb2 base material. The MgO protective layer is deposited on the surface of the Mg3Sb2 substrate, so that the Mg3Sb2-based thermoelectric material can be well protected from chemical reaction with oxygen and water in the air; meanwhile, Mg loss at high temperature can be prevented, and performance reduction of the material after long-time operation at high temperature is prevented; moreover, the MgO protective layer and the Mg3Sb2-based material do not have chemical reaction, the interface is clear, and the performance of the thermoelectric material is not affected.
本发明提供了一种具有良好热稳定性的Mg3Sb2基热电材料及其制备方法，属于热电材料技术领域。本发明提供的具有良好热稳定性的Mg3Sb2基热电材料，包括Mg3Sb2基材和沉积在所述Mg3Sb2基材表面的MgO保护层。本发明在Mg3Sb2基材表面沉积有一层MgO保护层，可以很好地保护Mg3Sb2基热电材料不与空气中的氧气和水发生化学反应；同时还可以阻止高温下的Mg损失，防止材料高温下长时间运行后性能下降；而且，MgO保护层与Mg3Sb2基材料不发生化学反应，界面清晰，不会影响热电材料本身性能。
