This iridium evaporation material requires e-beam deposition with a water-cooled copper hearth and a compatible liner. The material's high melting point and density impose specific process parameter constraints for stable film formation.
- Deposition Source Compatibility: Evaporation must be performed using e-beam deposition with a water-cooled copper hearth and a compatible liner material such as graphite, Al2O3, BN, or Ta.
- Piece Size Compatibility: The 3-6 mm piece size must be confirmed compatible with the deposition source geometry and crucible dimensions.
- Process Parameter Constraints: Process parameters must account for the material's melting point of 2410°C, density of 22.42 g/cm³, and Z-ratio of 0.129 to achieve stable evaporation rates.
- Purity and Form Verification: Material purity of 99.99% and physical form as pieces must be verified against the intended thin-film application requirements.
- Pre-Order Confirmation: Before ordering, the user must confirm the pack size, certificate requirements, and shipment conditions based on laboratory use.
How does the Z-Ratio of iridium evaporation material affect thickness monitoring during e-beam deposition?
The Z-Ratio of iridium is specified as 0.129. This value is critical for calibrating quartz crystal microbalance (QCM) sensors used in e-beam evaporation; a lower Z-Ratio indicates a larger frequency shift per deposited mass compared to gold (Z=1), requiring proper tooling factor adjustment to avoid systematic thickness errors in thin-film coatings.
Which crucible liner materials are recommended for evaporating iridium pieces in an e-beam system?
For e-beam evaporation of iridium pieces at its high melting point (~2410°C), compatible crucible liners include graphite (graphite), alumina (Al2O3), boron nitride (BN), and tantalum (Ta). These materials withstand thermal stress without contaminating the melt; a water-cooled copper hearth is also standard to prevent liner degradation.
What are the implications of iridium's high melting point for e-beam evaporation process parameters?
Iridium has a melting point of approximately 2410°C as stated in the specifications. This requires substantial electron beam power to achieve practical evaporation rates; the water-cooled copper hearth must efficiently dissipate heat to prevent thermal runaway or hearth damage. Process parameters such as beam current sweep pattern must be optimized accordingly.
This Iridium evaporation material (99.99%, 3-6 mm pieces) offers high purity and controlled morphology for e-beam deposition, but its high melting point and density demand specialized hardware and process calibration.
Positive
- High Purity (99.99%): Specified 99.99% purity ensures minimal impurity incorporation in thin films, critical for applications in catalysis, electronics, and corrosion-resistant coatings.
- Controlled Piece Size (3-6 mm): Uniform 3-6 mm pieces facilitate consistent material loading into e-beam hearths and promote stable evaporation rates.
Trade-offs
- High Melting Point (2,410°C): Requires high-power e-beam evaporation and robust thermal management; may limit compatibility with lower-temperature deposition systems.
- High Density and Low Z-Ratio: With density 22.42 g/cm³ and Z-ratio 0.129, careful process calibration is needed for accurate thickness monitoring via quartz crystal microbalance.
