This material must be used with evaporation sources compatible with manganese, such as Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths. Deposition parameters must be matched to the material's melting point, density, and Z-ratio to ensure proper thin-film formation.
- Compatible Evaporation Sources: Suitable for use with Mo/W/Ta boats, graphite/alumina crucibles, and e-beam hearths.
- Evaporation Method Compatibility: Applicable to thermal/resistive and e-beam evaporation processes.
- Process Matching Requirement: Deposition parameters must be matched to the material's melting point (1,244°C), density (7.2 g/cm³), and Z-ratio (0.377).
- Particle Size for Loading: The 3-6 mm piece size is designed for direct loading into evaporation sources.
How does the Z-ratio of 0.377 for manganese influence the choice between thermal and e-beam evaporation and the need for rate feedback control?
The Z-ratio of 0.377 indicates a low acoustic impedance mismatch, which is favorable for e-beam evaporation using quartz crystal monitoring. For thermal evaporation, the low melting point of 1,244°C allows resistive heating, but the Z-ratio should be considered for accurate film thickness control. The product supports both thermal/resistive and e-beam evaporation methods.
What are the recommended crucible or boat materials for evaporating manganese to avoid contamination or alloying?
The product is compatible with Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths. Manganese can wet and alloy with refractory metals such as molybdenum and tungsten; therefore, graphite or alumina crucibles are often preferred for thermal evaporation to prevent boat degradation and contamination of the film.
Why is the manganese supplied as 3-6 mm pieces rather than powder or larger lumps for vacuum deposition?
The 3-6 mm piece size is specified to facilitate controlled source loading and consistent evaporation rate. Larger pieces can cause uneven heating and poor thermal contact, while powder increases dust risk and may lead to undesirable vaporization bursts. The source explicitly states that this sizing supports source loading and evaporation review.
This manganese evaporation material (99.99% purity, 3-6 mm pieces) is designed for thermal and e-beam deposition with wide crucible compatibility, but requires meticulous pre-quotation verification of source geometry and process conditions to ensure successful film growth.
Positive
- High-purity 99.99% manganese pieces: The material is supplied as 99.99% pure manganese pieces in a 3-6 mm size range, ensuring consistent identity and form for vacuum thin-film deposition processes.
- Multiple evaporation source compatibility: Compatible with thermal/resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles, as well as e-beam evaporation, providing flexibility in deposition hardware selection.
Trade-offs
- Pre-quotation verification required: Buyers must confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before quotation to ensure compatibility with laboratory workflows.
- Deposition process matching needed: Evaporation source hardware and process route must be matched to manganese's melting point (1244°C), density (7.2 g/cm³), and film requirements to achieve desired deposition outcomes.
