This magnesium evaporation material must be used with a compatible boat or crucible material to avoid contamination and ensure proper evaporation. The pellets require thermal or resistive heating as the primary evaporation method, with low-power electron beam as an optional alternative.
- Crucible compatibility: The material requires a boat made of molybdenum, tungsten, or tantalum, or a crucible of graphite or alumina.
- Evaporation method: Thermal or resistive evaporation is preferred; low-power electron beam evaporation is optional but may require process adjustments.
- Pellet size handling: The 3-6 mm pellet size must be compatible with the source loading geometry to ensure uniform deposition.
- Melting point consideration: The evaporation temperature must exceed the material's melting point of 649°C to achieve proper vaporization.
- Thickness monitoring: The Z-ratio of 1.61 must be used for quartz crystal microbalance calibration to accurately measure film thickness.
What does a Z-Ratio of 1.61 indicate when using these magnesium pellets with a quartz crystal microbalance?
The Z-Ratio of 1.61 is a material-specific correction factor used with quartz crystal microbalance sensors during thin-film deposition monitoring. For these magnesium pellets with density of 1.74 g/cm³ and melting point of approximately 649°C (as stated), it accounts for acoustic impedance mismatch between magnesium and quartz crystal sensor material ensuring accurate film thickness measurement during thermal evaporation processes.
Which boat or crucible materials are recommended by Atomfair® when evaporating these magnesium pellets?
According to specifications recommended evaporation sources are molybdenum (Mo), tungsten (W), tantalum (Ta) boats as well as graphite or alumina crucibles while thermal/resistive evaporation method is preferred over low-power e-beam optional method requiring careful source geometry matching during deposition process setup.
What pack sizes are available and what is indicative pricing structure?
Available pack sizes are minimum order quantity of one hundred grams up through five hundred grams and one kilogram packages with indicative prices being four hundred fifty US dollars one thousand two hundred US dollars one thousand six hundred fifty US dollars respectively.
Magnesium evaporation pellets (99.9%, 3-6 mm) provide a defined physical form and purity for thermal resistive evaporation, but require careful matching of source hardware (Mo/W/Ta boat or graphite/alumina crucible) and process control due to the low melting point and density of the material.
Positive
- High purity and defined pellet size: The 99.9% purity and 3-6 mm pellet form ensure consistent material feeding and reproducible evaporation rates in vacuum deposition systems.
- Flexible evaporation source compatibility: Compatible with Mo/W/Ta boats or graphite/alumina crucibles, supporting both thermal resistive and low-power e-beam evaporation methods.
Trade-offs
- Low melting point requires process control: With a melting point of 649°C, precise temperature control is needed to avoid rapid evaporation or source damage; the low density (1.74 g/cm³) may affect pellet packing and evaporation uniformity.
- Pre-deployment compatibility verification required: Buyers must confirm deposition source geometry, pack size, and certification requirements prior to ordering, as the material's behavior is sensitive to source hardware and process conditions.
