Tungsten Selenide Properties
Properties of Tungsten Selenide WSe2 Powder:
Tungsten diselenide is the most thermally insulating material found so far In general, the material with the worst thermal conductivity (or thermal insulator) is a so-called porous material.
The thermal conductivity of tungsten diselenide film is worse than that of single crystal tungsten diselenide. Probably only one ten thousandth of the diamond with the best thermal conductivity. This new material not only has a thermal conductivity like a porous substance. More importantly, its density is very high. Probably similar to copper.
