| 摘要: |
| 羰基钨是金属钨与羰基所形成的配合物，它能在较低的温度下挥发和解离，通过控制羰基钨的热解方式、解离时间、气氛等可以制备出各种新型材料，羰基钨在新材料的合成和制备中发挥着十分重要的作用。文中介绍了利用羰基钨制备微米、纳米级粉体、薄膜、异形件的研究进展，阐述了羰基钨热解的原理，并对羰基钨在羰基钨复合膜材料、大型钨器件等方面的应用进行了展望。 |

| Abstract: |
| Tungsten hexacarbonyl is a coordination compound consisting of tungsten and carbonyl. It can be evaporated and dissociated at a very low temperature. Tungsten hexacarbonyl is very important to prepare advanced material by controlling dissociation way, time, atmosphere, and so on. In this paper, the recent progress of tungsten powder, films and device is reviewed. The principle of thermal dissociation of tungsten hexacarbonyl is described. Besides, the future development of tungsten hexacarbonyl composite films, large–scale tungsten device is also prospected. |
