This material requires E-beam evaporation with a compatible liner and high-temperature crucible for thermal processing. The powder's 10 µm particle size and 800°C melting point dictate specific handling and processing conditions.
- Deposition Method Compatibility: E-beam evaporation is the preferred method; thermal evaporation feasibility requires a request for quotation (RFQ) and use of a high-temperature crucible such as Al2O3.
- Crucible and Liner Requirements: The evaporation source must use an E-beam hearth with a compatible liner and a high-temperature crucible, with Al2O3 specified as a reference liner material.
- Particle Size and Form Handling: The powder with 10 µm particle size requires careful handling to avoid agglomeration and ensure uniform loading into the evaporation source.
- Melting Point and Thermal Behavior: The material's melting point of 800°C must be considered for evaporation rate control and to prevent thermal decomposition.
- Process Matching: Deposition source hardware and process parameters must be matched to the material's behavior, melting point, and target film requirements.
What is the purity grade of this GaN evaporation material, and how does it compare to higher-purity alternatives available for research applications?
This GaN powder is supplied at 99.4% purity, which is a standard research grade. The product description indicates that higher-purity and RFQ-controlled grades are available for comparison, though specific figures are not listed. Buyers requiring higher purity should submit an RFQ to discuss specifications and cost implications.
Is this GaN powder suitable for thermal evaporation, or is e-beam evaporation required?
E-beam evaporation is the preferred method for this GaN powder, as stated in the specification. Thermal evaporation feasibility requires an RFQ, as the material's melting point of 800°C and powder form may demand a high-temperature crucible (e.g., Al2O3) and process optimization.
What crucible or liner material is recommended for e-beam evaporation of this GaN powder?
The recommended liner material for the e-beam hearth is Al2O3 (alumina). For high-temperature crucible applications, an RFQ is required to confirm compatibility with the specific deposition hardware. The density of 6.1 g/cm³ should also be considered when selecting crucible volume.
Gallium Nitride (GaN) evaporation material, 99.4% purity, 10 µm powder, available in 25g to 1kg packs, optimized for E-beam evaporation with RFQ needed for thermal feasibility.
Positive
- Defined material identity and purity: Gallium Nitride (GaN) with 99.4% purity and 10 µm powder sizing provide clear specification for precise deposition-process matching.
- Specified physical form for consistent deposition: The powder form with 10 µm particle size supports reliable source loading and evaporation behavior in vacuum thin-film deposition workflows.
Trade-offs
- E-beam evaporation preferred; thermal feasibility by RFQ: The material is optimized for E-beam evaporation; thermal evaporation is not standard and requires a separate RFQ for feasibility assessment, potentially delaying procurement.
- Deposition source compatibility must be confirmed: Evaporation hardware must be matched to the material's behavior and melting point; buyers must verify E-beam hearth liner compatibility or request high-temperature crucible via RFQ before ordering.
