Deposition of this MgO powder requires strict adherence to source hardware compatibility and process method selection to avoid material waste and film defects. The high melting point (2852°C) and Z-ratio (0.411) demand specific liner or boat materials and favor e-beam evaporation over thermal evaporation without prior qualification.
- Evaporation Method Constraint: E-beam evaporation is the preferred method for this MgO powder, while thermal evaporation requires a request for quotation due to material-specific process considerations.
- Liner Material Compatibility: The e-beam hearth must be lined with graphite, aluminum oxide, or boron nitride to prevent contamination and ensure proper heat transfer.
- Boat Material Compatibility: For thermal evaporation, boats made of tungsten, molybdenum, or tantalum are required to withstand the high melting point of MgO.
- Particle Size Influence: The 35 nm particle size affects powder flow and source loading, requiring careful handling to maintain deposition consistency.
- Purity Verification: The 99.95% purity specification must be verified via certificate of analysis to confirm suitability for high-quality thin-film deposition.
What is the significance of the Z-Ratio of 0.411 for MgO evaporation material?
The Z-Ratio of 0.411 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring during e-beam evaporation. It indicates the acoustic impedance mismatch between the MgO film and the quartz crystal, requiring a tooling factor adjustment for accurate film thickness measurement. The product specification explicitly lists this Z-Ratio, which engineers must input into their deposition controller for reliable rate control.
Which liner and boat materials are compatible with MgO evaporation in an e-beam system?
The source specifies that MgO can be evaporated from an e-beam hearth using a graphite, Al2O3, or BN liner, or alternatively from a W, Mo, or Ta boat. The recommended liner material is graphite (Sheet2 hardware: Graphite). This compatibility guidance is provided to ensure thermal stability and avoid chemical reaction between the melt and crucible, particularly at the high melting point of 2,852°C.
What melting point considerations are there for e-beam evaporation of this MgO powder?
The melting point of MgO is 2,852°C, as stated in the specifications. This high melting point requires a high-power e-beam source and a liner material that can withstand such temperatures without contaminating the melt. The product is recommended for e-beam evaporation (performance: Good) and the listed liner materials (graphite, Al2O3, BN) are selected for their thermal stability at this temperature.
This MgO evaporation material (99.95% purity, 35 nm powder) is optimized for E-beam thin-film deposition. The high melting point (2,852°C) and Z-ratio of 0.411 require compatible source hardware (graphite/Al2O3/BN liners or W/Mo/Ta boats), while the fine powder form demands careful handling to avoid contamination and ensure uniform loading.
Positive
- High Purity and Defined Particle Size: 99.95% purity and 35 nm particle size enable consistent evaporation behavior and film quality for research-grade applications.
- E-Beam Evaporation Compatibility: Rated as 'Good' for E-beam evaporation with standard liner materials (graphite, Al2O3, BN) or refractory metal boats, supporting reliable deposition.
Trade-offs
- Powder Handling Sensitivity: The fine 35 nm powder form requires careful handling to prevent airborne contamination and ensure uniform loading into crucibles or hearths.
- Limited Thermal Evaporation Flexibility: Thermal evaporation is not standard and requires RFQ, constraining process options for labs without E-beam capability.
