Aluminium evaporation pellets require vacuum deposition using thermal/resistive or e-beam methods. Source compatibility with Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths must be confirmed before use.
- Evaporation Method: Aluminium pellets are intended for thermal/resistive or e-beam evaporation under vacuum conditions.
- Source Hardware Compatibility: Select compatible source hardware such as Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths to avoid contamination.
- Process Parameter Matching: Match evaporation source and process parameters to the material melting point (660°C), density (2.7 g/cm³), and Z-ratio (1.08) for consistent film deposition.
- Pre-Use Verification: Confirm material identity, purity, form, size range, and pack size before integrating into the deposition run.
What is the Z-ratio of 1.08 for this aluminium evaporation material and how is it used in deposition?
The Z-ratio of 1.08 is a tooling factor used with quartz crystal microbalance (QCM) monitors to accurately measure and control film thickness during e-beam evaporation. It is derived from the material's density (2.7 g/cm³) and acoustic impedance, and this value is specific to 99.99% pure aluminium pellets. Correctly setting the Z-ratio in the deposition controller ensures precise rate and thickness control.
Which boats or crucibles are compatible with these 99.99% aluminium evaporation pellets?
This aluminium pellet material is compatible with Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths, as stated in the technical specifications. These hardware options support both thermal/resistive and e-beam evaporation methods, allowing the pellets to be used across common vacuum deposition systems. Buyers should confirm their specific source geometry and material compatibility before ordering.
What are the melting point and density of this aluminium evaporation material, and how do they affect the deposition process?
The melting point is 660°C and the density is 2.7 g/cm³, as listed in the technical specifications. The relatively low melting point allows efficient thermal evaporation at moderate temperatures, reducing thermal stress on crucibles, while the density informs material loading calculations and the required source charge volume. Both parameters are critical for matching the material to the evaporation method and hardware.
This 99.99% pure aluminium pellet material with 1-3 mm particle size is designed for thermal and e-beam evaporation in vacuum deposition systems, offering consistent film quality with specified compatibility for Mo/W/Ta boats and crucibles.
Positive
- High purity 99.99% specification: The 99.99% purity grade ensures minimal contamination in deposited thin films, suitable for sensitive electronic and optical coatings.
- Optimized pellet size 1-3 mm: The pellet form and 1-3 mm size range provide controlled loading and consistent evaporation rates in thermal and e-beam sources.
Trade-offs
- Evaporation source compatibility required: Buyers must confirm deposition source hardware (boat, crucible, or hearth) matches the material's melting point and evaporation behavior to avoid process failure.
- Process parameters must be matched: The melting point of 660°C and density of 2.7 g/cm³ require precise temperature and deposition rate control to achieve uniform film thickness and avoid spitting.
