General

Tantalum oxide is an inorganic chemical compound with a chemical formula of Ta2O5. It is crystalline solid and white in appearance with a density of 8.2 g/cc, a melting point of 1,872°C, and a vapor pressure of 10-4 Torr at 1,920°C. It is mainly used to produce capacitors which can be found in auto electronics, cell phones, and tools. Tantalum oxide can also be found in the glass for camera lenses. It is evaporated under vacuum to form films for the fabrication of semiconductors, optoelectronic devices, and fuel cells.

Starter Sources Table

Starter sources can be used in place of pellets for e-beam evaporation. These sources are pre-machined or pre-melted slugs that can be used in conjunction with either a crucible liner or placed directly in the copper hearth of an e-gun. Once the starter source begins to deplete, they can be topped off with additional pellets. The main benefits of starters sources are superior packing density and ease of use. In order to quote a starter source, please contact international@lesker.com with your e-gun manufacturer and pocket size.
