This material must be processed via E-beam evaporation using a graphite, Al2O3, or BN liner or a W/Mo/Ta boat to ensure compatibility. Thermal evaporation requires prior RFQ approval due to material behavior at elevated temperatures.
- Evaporation Source Compatibility: The tablet form (6 mm) requires a compatible hearth liner or boat to maintain thermal contact and prevent mechanical failure.
- Melting Point Constraint: The material melts at 1,872°C and requires a heating source capable of sustaining that temperature without degrading the crucible.
- Density and Z-Ratio Influence: The density of 8.2 g/cm³ and Z-ratio of 0.3 affect deposition rate monitoring and film thickness calibration during E-beam evaporation.
- Purity Verification: The specified 99.9% purity must be verified against the deposition requirements to avoid introducing contaminants into the film.
- Source Geometry Matching: The tablet size (6 mm) must be matched to the source pocket dimensions to ensure uniform evaporation and prevent material ejection.
What makes Ta2O5 tablets with 99.9% purity suitable for e-beam evaporation in thin-film deposition?
Ta2O5 has a melting point of 1,872 °C, density of 8.2 g/cm³, and Z-ratio of 0.3, making it appropriate for e-beam evaporation with graphite/Al2O3/BN liners or W/Mo/Ta boats. The 99.9% purity ensures minimal contamination for optical and electronic thin films.
Which evaporation source and liner materials are compatible with 6 mm Ta2O5 tablets for vacuum deposition?
The primary recommended method is e-beam evaporation with a hearth liner of graphite, Al2O3, or BN, or using a W/Mo/Ta boat. Sheet2 hardware can use Tantalum. Thermal evaporation is available by RFQ. The tablet form factor (6 mm) is designed for standard e-beam pocket geometry.
What procurement checks are essential when ordering Ta2O5 evaporation material in tablet form?
Before quotation, confirm model (AF-TA2O5TAB-3N6MM), purity (99.9%), form (tablet), size (6 mm), required pack size (25g to 1kg), and deposition-source compatibility. Review certificate of analysis, safety data sheet, shipment conditions, and export requirements for laboratory use.
Ta2O5 99.9% tablet evaporation material (6 mm) provides controlled purity and form for E-beam deposition, but requires high-temperature source compatibility and preferred E-beam method, with thermal evaporation limited to RFQ.
Positive
- High purity 99.9%: The 99.9% purity specification supports reproducible thin-film stoichiometry and minimizes contamination in optical or dielectric coatings.
- Tablet form 6 mm: Supplied as 6 mm tablets, facilitating consistent source loading, stable evaporation rates, and compatibility with standard E-beam hearths.
Trade-offs
- E-beam preferred, thermal limited: E-beam evaporation is the recommended method with good performance; thermal evaporation requires RFQ, restricting process flexibility for users without E-beam capability.
- High melting point requires specialized sources: Melting point of 1,872 °C necessitates high-temperature source liners (graphite/Al2O3/BN) or W/Mo/Ta boats, increasing hardware and operational complexity.
