Product Overview
This Puratronic™ indium foil delivers exceptional purity at 99.9975% (metals basis), making it a premium choice for demanding laboratory applications where trace impurities can compromise results. The 0.1mm (0.004in) thickness provides an optimal balance between flexibility and structural integrity, allowing for easy handling while maintaining dimensional stability. Engineered for consistency, this foil undergoes rigorous quality control to ensure uniform thickness and surface finish across each sheet. Its high-purity composition minimizes contamination risks in sensitive experiments, particularly in semiconductor research, thin-film deposition, and calibration processes. The foil’s malleability enables precise cutting and shaping without cracking, while its low melting point (156.6°C) makes it suitable for thermal bonding applications. Available in standard 100x100mm and 50x50mm sizes, this indium foil comes packaged to prevent oxidation and surface degradation during storage. The Puratronic™ grade certification guarantees traceability and batch-to-batch reliability, critical for reproducible scientific outcomes. Unlike commercial-grade alternatives, this material meets ASTM F68-19 standards for high-purity metals, with certified analysis documentation available upon request.
FAQs
1. What is the difference between Puratronic™ and standard indium foil?
Puratronic™ indium foil undergoes additional purification steps to achieve 99.9975% purity, reducing trace metallic impurities that could interfere with sensitive applications. Standard grades typically range between 99.9% and 99.99% purity.
2. Can this foil be used for thermal interface material applications?
The 0.1mm thickness and high purity make it suitable for thermal interface applications where minimal electrical conductivity and high thermal transfer are required, though specialized thermal pastes may offer better performance in some cases.
3. How should I store unused indium foil to prevent oxidation?
Store in its original packaging or an airtight container with desiccant packets in a cool, dry environment. Avoid exposure to moisture or acidic vapors, which can accelerate surface oxidation.
4. Is this foil compatible with vacuum deposition systems?
Yes, the high purity and low outgassing properties make it compatible with most vacuum deposition systems, though you may need to pre-clean the surface depending on your specific chamber requirements.
5. What alternatives exist for applications requiring thicker indium sheets?
For thicker requirements, consider indium sheets (0.5mm-3mm) or indium blocks, though these may require machining. Thinner alternatives include indium wire or sputter targets for different application needs.
