| Empirical formula | NbSe2 |
| Assay | ≥99.9% trace metals basis |
| Application | NbSe2 is a layered hexagonal metal dichalcogenide with metallic properties and a large work function. This makes it a potential candidate as back contact material for thin film solar cells.Layered materials have drawn considerable attention because of their possible exfoliation into single and multilayer 2-dimensional sheets. Because of strong surface effects, the properties of these materials vary drastically with the nunber of layers in a sheet. |
| Melting point | >1316 °C(lit.) |
