以钼为基体的铝复合材料是热电子能量转换的侯选电极材料。荷兰埃因霍温科技大学技术陶瓷中心研究的这种复合材料是将 Al_2O_3和钼粉混合物在真空中烧结而制得的。将复合材料表面抛光后,于1400℃的铯气氛中(10~2Pa)加热2000h。加热后,复合材料-气体界面处不存在 Al_2O_3,钼基体表面亦不存在铝,Al_2O_3颗粒存在于大块的
Aluminum-based molybdenum composites are candidate electrode materials for thermoelectron energy conversion. The composite material studied by Technical Ceramics Center, Eindhoven University in the Netherlands, was prepared by sintering a mixture of Al 2 O 3 and molybdenum powder in a vacuum. After polishing the surface of the composite material, the composite material is heated in a cesium atmosphere (10-2 Pa) at 1400 DEG C for 2000 hours. After heating, Al 2 O 3 did not exist at the interface between the composite material and the gas, aluminum did not exist on the surface of the molybdenum substrate, and Al 2 O 3 particles existed in the bulk
