Vanadium evaporation pellets require loading into a water-cooled copper e-beam hearth with a compatible graphite, Al2O3, BN, or Ta liner. The material's melting point of 1890°C, density of 5.96 g/cm³, and Z-ratio of 0.53 dictate evaporation parameters and must be matched to the deposition source geometry and process.
- Evaporation Source Compatibility: Use only water-cooled copper e-beam hearth with graphite, Al2O3, BN, or Ta liner; incompatible liners may cause contamination or hearth damage.
- Pellet Size Constraint: Confirm that the 3-6 mm pellet diameter fits the source crucible or liner opening to avoid loading issues.
- Purity Verification: Verify the 99.9% purity through certificate of analysis to ensure consistent film stoichiometry during evaporation.
- Melting Point Impact: Adjust evaporation power and rate to account for the 1890°C melting point to prevent spitting or incomplete evaporation.
- Z-Ratio Calibration: Set the thickness monitor to the Z-ratio of 0.53 for accurate film thickness measurement during deposition.
Why does the vanadium evaporation material have a Z-ratio of 0.53 and how does it affect e-beam evaporation process control?
The Z-ratio of 0.53 is the acoustic impedance factor for vanadium, used in quartz crystal microbalance thickness monitoring during e-beam evaporation. The product specification lists this value to enable accurate deposition rate calibration and film thickness control. E-beam evaporation is the preferred method, and the source notes a water-cooled copper hearth with compatible liners (graphite, Al2O3, BN, Ta) to handle the material's melting point of 1,890°C.
What liner materials are compatible with vanadium evaporation in an e-beam system?
Compatible liner materials for the e-beam hearth include graphite, Al2O3, BN, and Ta, as stated in the product specifications. The primary evaporation source is a water-cooled copper e-beam hearth, and these liners are selected for thermal stability and chemical compatibility with molten vanadium at its melting point of 1,890°C.
What is the recommended particle size range for vanadium pellets to ensure consistent evaporation in e-beam sources?
The product is supplied as pellets in a 3–6 mm size range, as specified in the technical data. This size distribution is intended to support uniform source loading and controlled evaporation, avoiding issues like incomplete melting or splashing in the e-beam hearth. The pellets are 99.9% pure vanadium, and the form factor is optimized for vacuum thin-film deposition workflows.
Vanadium (V) evaporation pellets at 99.9% purity and 3-6 mm size are supplied for e-beam deposition, with defined material identity, physical form, and compatible hearth liner options, but require careful matching of deposition hardware and process parameters to achieve consistent film quality.
Positive
- Defined material identity and purity: Vanadium (V) pellets with 99.9% purity and 3-6 mm size range ensure traceable procurement and consistent deposition source loading for vacuum thin-film workflows.
- Compatible with e-beam evaporation liners: Compatible with water-cooled copper e-beam hearth and graphite/Al2O3/BN/Ta liners, offering flexibility in deposition source configuration.
Trade-offs
- Deposition source matching required: Evaporation source hardware and process route must be matched to the material's melting point (1,890°C), density (5.96 g/cm³), and Z-ratio (0.53) to ensure proper film deposition and rate control.
- Compatibility verification before use: Buyers must confirm model, purity, form, size, and deposition-source compatibility with their specific equipment before quotation, as material behavior varies with process parameters.
