This yttrium oxide evaporation material requires specific source hardware and evaporation methods to achieve optimal thin-film deposition. The material's high melting point and particle size impose constraints on source selection and loading procedures.
- Evaporation Source Compatibility: The material must be used in an E-beam hearth with a graphite, alumina, or boron nitride liner, or in a tungsten, molybdenum, or tantalum boat.
- Evaporation Method Preference: E-beam evaporation is the preferred method; thermal evaporation requires a request for quotation to ensure compatibility.
- Melting Point Requirement: The high melting point of 2410°C necessitates evaporation sources capable of sustained high-temperature operation.
- Particle Size Consideration: The 325 mesh particle size influences source loading uniformity and evaporation rate consistency.
- Pre-Use Verification: Deposition-source hardware compatibility must be confirmed before quotation to avoid material waste or process failure.
Why is Yttrium Oxide for evaporation supplied as 325 mesh pieces instead of a different form factor like powder or dense pellets?
The 325 mesh pieces form is specifically selected to optimize e-beam evaporation performance. Pieces enable controlled loading into the hearth and minimize outgassing issues compared to fine powders, while the specified mesh size ensures consistent particle size distribution for uniform evaporation. The source confirms a Good e-beam performance rating for this form factor.
What liner or boat materials are compatible with e-beam evaporation of Yttrium Oxide (Y2O3)?
Yttrium Oxide pieces are compatible with e-beam hearth liners made of graphite, aluminum oxide (Al2O3), or boron nitride (BN), as well as boats fabricated from tungsten (W), molybdenum (Mo), or tantalum (Ta). The product’s hardware specification also lists graphite and tungsten as approved sheet2 materials. These options ensure thermal and chemical compatibility during high-temperature evaporation.
Is thermal evaporation a viable alternative to e-beam for Yttrium Oxide deposition?
E-beam evaporation is the preferred method for Y2O3 due to its high melting point of 2,410°C and corresponding energy requirements. Thermal evaporation is not a standard option and would require a formal request for quotation (RFQ) to evaluate boat material compatibility, power density, and process stability. Buyers should expect that thermal routes need custom validation.
Yttrium Oxide (Y2O3) evaporation material in pieces at 99.999% purity and 325 mesh size is evaluated for E-beam evaporation with good performance using graphite, Al2O3, or BN liners, or W/Mo/Ta boats, with a melting point of 2,410°C and density of 5.01 g/cm³.
Positive
- High purity for thin-film integrity: The 99.999% purity specification minimizes contamination in deposited films, critical for optical and electronic applications where impurity levels affect performance.
- Defined physical form for source loading: Supplied as pieces at 325 mesh, this form factor facilitates consistent loading into E-beam hearths or boats, supporting reproducible deposition rates.
Trade-offs
- E-beam preferred; thermal by RFQ only: E-beam evaporation is the recommended method with good performance, while thermal evaporation requires a request for quotation, limiting process flexibility without prior confirmation.
- High melting point requires robust hardware: With a melting point of 2,410°C, this material demands compatible liner materials (graphite, Al2O3, BN) or refractory metal boats (W, Mo, Ta), increasing infrastructure requirements for standard labs.
