Dispersibility of W Species on the Surface of W/ TiO_2 Catalysts

W/TiO2催化剂表面上钨的分散性

The dispersion property of W species on the surface of Al-CLM or γ-Al 2O 3 catalysts prepared by impregnation method is better than that of mixed-heating method when their W contents are the same.

同时，对于W/Al-CLM催化剂和W/γ-Al2O3催化剂，在相同钨含量情况下，均是浸渍法催化剂表面上钨物种的分散性优于干混法。

The arc erosion of CuW70/ CrCu integrated contact is first from the even volatilization of the surface Cu, following by the formation of a W shell on the surface of W skeleton, then the shell flake off, after this, new arc erosion occur.

CuW70的烧损先是表层的Cu均匀挥发，接着在骨架的表面形成一层以W为主的壳层，然后壳层剥落，裸露出来的继续烧损，如此反复，导致了触头的烧损。
