This evaporation material requires a compatible source boat or crucible, such as molybdenum, tungsten, tantalum, graphite, or alumina. Thermal or resistive evaporation is the preferred method, with low-power electron beam evaporation as an optional alternative.
- Source Compatibility: Evaporation source hardware must be matched to the material's melting point (649 °C) and Z-ratio (1.61) to ensure film quality.
- Pellet Size Considerations: The pellet size range of 3-6 mm is designed for loading into thermal evaporation sources and must be confirmed against source geometry.
- Process Parameter Adjustment: Process parameters should be adjusted based on material behavior, melting point, and required film properties.
- Procurement Confirmation: Buyers must verify deposition source compatibility, certificate requirements, and shipment conditions before ordering.
Why is thermal/resistive evaporation preferred over e-beam for these magnesium pellets?
Thermal/resistive evaporation is preferred because magnesium has a relatively low melting point of 649°C and high vapor pressure at moderate temperatures; low-power e-beam is listed as optional but requires careful control using Mo/W/Ta boats or graphite/alumina crucibles to avoid overheating due to magnesium's low density (1.74 g/cm³). The specified boat materials are optimized for resistive heating sources.
What crucible or boat materials are compatible with evaporating these magnesium pellets?
Compatible evaporation sources include molybdenum (Mo), tungsten (W), or tantalum (Ta) boats as well as graphite or alumina crucibles. These materials withstand the magnesium melting point of 649°C without contamination and are suitable for both thermal/resistive and low-power e-beam methods as stated in the product specifications.
How does the Z-Ratio of 1.61 affect deposition rate monitoring for this magnesium material?
The Z-Ratio of 1.61 is used in quartz crystal microbalance (QCM) sensors to correct for acoustic impedance mismatch between the deposited magnesium film and the quartz crystal; this ensures accurate thickness monitoring during evaporation. Incorrect Z-Ratio settings can lead to film thickness errors of several percent for materials like magnesium with a density of 1.74 g/cm³.
Magnesium (Mg) evaporation material in pellet form with 99.99% purity and 3-6 mm size range, suitable for thermal/resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles. The low melting point (649°C) and low density (1.74 g/cm³) require careful process parameter optimization for uniform film deposition.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contamination in thin films, suitable for research-grade vacuum deposition.
- Controlled pellet form and size: The 3-6 mm pellet size allows consistent loading and evaporation in thermal boats, reducing process variability.
Trade-offs
- Deposition source compatibility must be verified: The buyer must confirm that the pellet size and form are compatible with their specific evaporation source hardware, as the material requires Mo/W/Ta boat or graphite/alumina crucible for thermal evaporation.
- Low melting point requires controlled parameters: With a melting point of 649°C, magnesium requires careful temperature and rate control during thermal evaporation to avoid spitting and ensure uniform film deposition.
