Magnesium oxide evaporation powder is processed via e-beam evaporation using graphite, alumina, or BN liners, or W/Mo/Ta boats. Thermal evaporation requires prior RFQ confirmation, and deposition hardware must be matched to the material's melting point and film requirements.
- Deposition method preference: E-beam evaporation is the preferred method; thermal evaporation requires prior RFQ confirmation.
- Liner compatibility: The material performs well with graphite, aluminum oxide, or boron nitride liners, or tungsten, molybdenum, or tantalum boats.
- Process matching requirement: Evaporation source hardware and process route must be matched to the material's melting point and film requirements.
What evaporation source and liner materials are compatible with MgO powder of 18 nm particle size for e-beam evaporation?
This MgO powder (99.95%, 18 nm) is designed for e-beam evaporation, which is the preferred method rated as 'Good'. Compatible source hardware includes an e-beam hearth with a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat. For sheet-type sources, graphite is specified as the compatible hardware. These liner and boat materials are chosen to withstand the high melting point of 2,852°C and prevent contamination during deposition.
How does the 18 nm particle size of this MgO powder influence deposition behavior compared to coarser or micron-sized powders?
The 18 nm particle size is a nanoscale powder, which provides a high surface-area-to-volume ratio. This can lead to more uniform evaporation rates and better film density in e-beam processes, but it also requires careful handling to avoid agglomeration and moisture absorption. The specified powder form with 18 nm sizing is intended to support source loading and evaporation review, and buyers must confirm deposition source geometry and handling conditions before use.
What purity and composition tolerance does the 99.95% MgO powder specification guarantee, and what qualification documentation is available?
The material is specified as 99.95% pure Magnesium Oxide (MgO), which is a standard research-grade purity level for thin-film evaporation. The product description indicates that a certificate of analysis, safety data sheet, and shipment condition documents can be reviewed against laboratory use requirements. Buyers should confirm certificate requirements before quotation to ensure the composition meets their application-specific impurity limits.
Magnesium Oxide (MgO) evaporation material, 99.95% purity, 18 nm powder form, designed for e-beam evaporation with good performance using graphite/Al2O3/BN liners or refractory metal boats; high melting point (2852°C) and moderate density (3.58 g/cm³) dictate specific deposition hardware and process conditions.
Positive
- High purity (99.95%): The 99.95% purity specification ensures minimal contamination in thin-film deposition, critical for reproducible optical or dielectric layer properties.
- Nano-sized powder (18 nm): The 18 nm particle size facilitates uniform source loading and consistent evaporation rates, particularly beneficial for controlled deposition of ultra-thin MgO films.
Trade-offs
- High melting point requires e-beam: With a melting point of 2852°C, thermal evaporation is not recommended without RFQ; e-beam evaporation with specific liners (graphite, Al2O3, BN) or refractory metal boats is mandatory, limiting deposition hardware flexibility.
- Liner and boat compatibility constraints: Optimal evaporation performance requires graphite/Al2O3/BN liners or W/Mo/Ta boats; incompatible crucible materials may cause contamination or poor adhesion, necessitating pre-confirmation of source geometry.
