Molybdenum evaporation material requires water-cooled copper e-beam hearth with compatible liners of graphite, Al2O3, BN, or Ta. Deposition-source compatibility and process route must be confirmed against material melting point and film requirements before use.
- Source Compatibility: Use only with water-cooled copper e-beam hearth and compatible liners such as graphite, Al2O3, BN, or Ta.
- Preferred Evaporation Method: E-beam evaporation is the preferred method for this material.
- Pre-Use Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before ordering.
- Process Matching: Match evaporation source hardware and process route to material behavior, melting point, and film requirements.
How does the Z-Ratio of 0.257 affect thickness monitoring during e-beam evaporation of Molybdenum?
The Z-Ratio of 0.257 must be entered into the quartz crystal microbalance (QCM) controller to correct for acoustic impedance mismatch between molybdenum and the quartz crystal sensor. Using an incorrect Z-Ratio leads to systematic thickness errors in deposited films; this value is specific to Mo at its stated density of 10.2 g/cm³.
What crucible liner materials are recommended for e-beam evaporation of Molybdenum at its melting point of 2617°C?
Compatible liners include graphite (for high-temperature stability), alumina (Al₂O₃), boron nitride (BN), and tantalum (Ta). These materials withstand the extreme melting point of molybdenum (2617°C) without reacting with molten Mo or contaminating the deposited film.
Why is the particle size of 1–3 mm specified for Molybdenum evaporation material?
The pieces size range of 1–3 mm ensures consistent packing density in the crucible and uniform melting under electron beam heating. Larger pieces may cause uneven melting while smaller particles risk spitting during evaporation; this size range is optimized for reliable e-beam deposition using a water-cooled copper hearth.
Molybdenum evaporation material (99.95%, 1-3 mm pieces) offers a defined high-purity source for e-beam deposition, with a melting point of 2,617°C, density of 10.2 g/cm³, and Z-ratio of 0.257 enabling precise process parameter matching.
Positive
- Defined high purity and physical form: 99.95% purity and 1-3 mm pieces ensure consistent evaporation behavior and source loading, critical for reproducible thin-film deposition in research workflows.
- Quantified material properties for process matching: Melting point (2,617°C), density (10.2 g/cm³), and Z-ratio (0.257) are provided, enabling accurate calibration of e-beam evaporation parameters and film thickness monitoring.
Trade-offs
- Restricted evaporation source compatibility: Designed primarily for water-cooled copper e-beam hearths with specific liner materials (graphite, Al2O3, BN, Ta); alternative evaporation methods may require hardware modifications or yield suboptimal results.
- High melting point imposes thermal management demands: At 2,617°C, the material requires significant e-beam power input and careful thermal control to avoid source damage or inconsistent deposition rates, particularly in smaller lab-scale systems.
