Niobium Evaporation Material 99.95% 1-3 mm ATOMFAIR®

Niobium pieces require e-beam evaporation with a water-cooled copper hearth and compatible liner materials such as graphite, alumina, BN, or tantalum. The 1-3 mm piece size and melting point of 2468°C must be matched to deposition source geometry and power capabilities.

• Evaporation Method: E-beam evaporation is the preferred method for this material.
• Liner Compatibility: Compatible liners include graphite, alumina, boron nitride, or tantalum.
• Size Constraint: The 1-3 mm pieces must fit the source crucible or hearth geometry.
• Thermal Constraint: Melting point of 2468°C requires sufficient e-beam power and cooling.
• Z-Ratio Consideration: Z-ratio of 0.492 must be used for thickness monitor calibration.

This Niobium evaporation material offers 99.95% purity in 1-3 mm pieces, suitable for e-beam evaporation with water-cooled copper hearth and compatible liners. Its high melting point (2468°C) and density (8.57 g/cm³) require careful process matching for vacuum thin-film deposition.

Positive

• High-purity pieces with defined size range: Specified 99.95% purity and 1-3 mm piece size support consistent source loading and deposition reproducibility, enabling direct comparison with standard or RFQ-controlled grades.
• Broad liner compatibility for e-beam evaporation: Compatible with graphite, Al2O3, BN, and Ta liners in a water-cooled copper e-beam hearth, providing flexibility in thermal management and contamination control.

Trade-offs

• High melting point requires robust evaporation setup: With a melting point of 2468°C, this material demands high-power e-beam sources and careful thermal management to achieve stable evaporation rates without overheating the hearth.
• Piece form necessitates deposition-source geometry verification: The 1-3 mm pieces must be loaded into the evaporation source, requiring confirmation that the hearth and liner dimensions accommodate the piece size to avoid bridging or uneven melting.
