Cell Lab 3N5 (99.95%) Tantalum (Ta) Wire Evaporation Materials [1 m Length]

High-Purity Refractory Metal Wire for Thin-Film and Optical Applications

General Description

Cell Lab 3N5 (99.95%) Tantalum (Ta) Wire is engineered for vacuum evaporation, thin-film coating, and high-temperature applications. Tantalum is a rare, hard, blue-grey transition metal known for its exceptional corrosion resistance, high melting point (3 017 °C), and mechanical strength.

As part of the refractory-metal family, it is ideal for use in semiconductor fabrication, x-ray optics, and superconducting thin-film research. Its purity and uniform geometry ensure clean evaporation and consistent deposition rates in both thermal and e-beam systems.

Key Features

  • Ultra-High Purity (99.95%) – Ensures minimal contamination and uniform thin-film composition.

  • Refractory Performance – Stable under extreme temperature and vacuum conditions.

  • Excellent Corrosion Resistance – Unaffected by most acids and aggressive environments.

  • E-Beam Compatible – Excellent evaporation stability with predictable vapour flux.

  • Custom Dimensions Available – Wire diameters and spool lengths tailored to specific system needs.

  • Laboratory R&D – Thin-film deposition in vacuum or controlled-atmosphere systems.

FAQ

Q1: Why is Tantalum preferred for vacuum evaporation?
Because of its high melting point, chemical inertness, and low vapour pressure, Tantalum provides extremely pure and stable deposition films.

Q2: Can this wire be used in E-Beam systems?
Yes – it offers excellent performance for E-Beam evaporation with graphite liners for stability and clean release.

Q3: Are other diameters or lengths available?
Yes – custom diameters and longer spools can be manufactured on request for industrial scale systems.

Q4: Is this wire suitable for superconducting research?
Absolutely – Tantalum films are often investigated for superconductivity due to their low resistance and stability.
