This material requires e-beam evaporation with specific hearth liner materials or thermal evaporation by RFQ. The fine powder form (<55 nm) necessitates careful handling to avoid dust dispersion and ensure uniform source loading.
- Deposition Source Compatibility: Use an e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat for thermal evaporation.
- Evaporation Method Preference: E-beam evaporation is the recommended method; thermal evaporation requires quotation review due to material behavior.
- High Melting Point Consideration: The melting point of 2852°C requires the evaporation source to sustain extreme temperatures without degradation.
- Fine Particle Handling: The powder particle size below 55 nm increases the risk of airborne dust; load in a controlled environment to prevent contamination.
What are the preferred evaporation methods and source hardware for MgO powder with <55 nm particle size?
E-beam evaporation is preferred, with good performance using an e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat. Thermal evaporation is available only by RFQ. The high melting point of 2,852 °C and density of 3.58 g/cm³ listed in the specifications make e-beam the recommended method for consistent deposition of this nanopowder.
Why is a graphite or Al2O3 liner recommended for MgO evaporation?
The product specification explicitly recommends graphite, Al2O3, or BN liners, or W/Mo/Ta boats for e-beam evaporation. Graphite is specifically indicated as the standard sheet hardware. This recommendation accounts for MgO's high melting point (2,852 °C) and chemical reactivity at deposition temperatures to avoid contamination and maintain source stability.
What handling and storage precautions are advised for MgO nanopowder (<55 nm) used in thin-film deposition?
Given the <55 nm particle size, the powder has high surface area and may be hygroscopic or prone to agglomeration. The product documentation includes a safety data sheet (SDS) and shipment conditions that should be reviewed before use. Buyers should confirm compatibility with their powder feed mechanism and storage environment, and request certificate analysis as needed.
Magnesium Oxide (MgO) evaporation material in powder form with 99.5% purity and sub-55 nm particle size is engineered for high-performance E-beam deposition, requiring specific liner or boat materials and infrastructure to handle its high melting point and fine powder characteristics.
Positive
- Defined purity and particle size: 99.5% purity and < 55 nm particle size provide traceable specification for consistent thin-film deposition and source-loading evaluation.
- Optimized for E-beam evaporation: Good E-beam performance with graphite, Al2O3, or BN liner compatibility enables reliable deposition without requiring thermal evaporation unless specified by RFQ.
Trade-offs
- Fine powder handling challenges: Sub-55 nm powder is prone to airborne dispersion and agglomeration, requiring controlled environment and proper handling protocols to avoid contamination and ensure uniform deposition.
- High melting point infrastructure need: Melting point of 2,852°C demands specialized E-beam hearth liners (graphite, Al2O3, BN) or W/Mo/Ta boats, increasing equipment and consumable requirements for lab deployment.
