This tantalum evaporation material requires e-beam evaporation using a compatible water-cooled copper hearth and liner. The material's high melting point and Z-ratio demand precise deposition parameter control to achieve desired film properties.
- Evaporation Source Compatibility: Must use water-cooled copper e-beam hearth with graphite, Al2O3, BN, or Ta liner.
- Evaporation Method: E-beam evaporation is the preferred deposition method for this material.
- Physical Form and Size: The material is supplied as 1-3 mm pieces to facilitate source loading and controlled evaporation.
- Thermal Requirement: The melting point of 2,996°C requires a high-temperature capable e-beam system.
- Process Control: The Z-ratio of 0.262 must be accounted for in deposition rate monitoring and calibration.
Why is e-beam evaporation recommended for tantalum pieces with a melting point of 2,996°C?
Tantalum's high melting point of 2,996°C requires e-beam evaporation to achieve the necessary energy density for vaporization. The water-cooled copper hearth prevents crucible melting and contamination, while the material's density of 16.6 g/cm³ and Z-ratio of 0.262 are provided for process calibration. This combination ensures reliable deposition of high-purity tantalum films.
Which liner materials are compatible with the water-cooled copper e-beam hearth for tantalum evaporation?
The product specification lists graphite, Al2O3, BN, and tantalum as compatible liner materials for the water-cooled copper e-beam hearth. Each liner offers different thermal and chemical properties; for example, graphite is suitable for high temperatures, while Al2O3 provides electrical insulation. Selection depends on process requirements and crucible geometry.
What pack sizes are available for tantalum evaporation material and how should they be selected?
Available pack sizes are 25g, 100g, 500g, and 1kg, with a minimum order quantity of 25g. The 1-3 mm piece size is designed to fit standard e-beam hearths, and pack size selection should account for the number of deposition runs, material consumption rate, and budget. Indicative pricing tiers are provided for each pack size to support procurement planning.
This Tantalum evaporation material (99.99% purity, 1-3 mm pieces) is suited for high-temperature e-beam deposition of dense, refractory metal films, but its high melting point and density impose specific infrastructure requirements.
Positive
- High purity 99.99%: Reduces contamination risk in thin-film deposition, enabling consistent film properties for research-grade applications.
- Controlled piece size 1-3 mm: Facilitates reliable loading into water-cooled copper e-beam hearths and compatible liners, improving evaporation uniformity.
Trade-offs
- High melting point 2,996°C: Requires robust e-beam evaporation capability and may limit substrate temperature tolerance or necessitate specialized handling.
- High density 16.6 g/cm³: Increases material weight per volume, affecting source loading procedures and requiring careful hearth design to avoid mechanical stress.
