Store powder in a dry, inert atmosphere to prevent oxidation and moisture uptake. Use water-cooled e-beam hearth with Al2O3 or graphite liner to avoid crucible contamination during deposition.
- Moisture Sensitivity: Exposure to ambient humidity may cause powder agglomeration and degrade evaporation uniformity.
- Crucible Compatibility: Thermal evaporation requires W or Ta boats by RFQ only; standard e-beam operation mandates Al2O3 or graphite liners to prevent alloy reaction with the hearth.
- Particle Size Constraint: 325 mesh powder must be loaded without compaction to maintain consistent vapor flux during e-beam evaporation.
This procedure covers safe loading and e-beam evaporation of Nichrome (Ni/Cr) 325 mesh powder. Confirm deposition source geometry and liner material before starting.
Required Equipment: Water-cooled e-beam hearth with Al2O3 or graphite liner, Inert-atmosphere glovebox or dry nitrogen purge
- Verify liner compatibility
Confirm the e-beam hearth liner is Al2O3 or graphite; do not use bare copper or steel crucibles. - Load powder under inert atmosphere
Transfer the 325 mesh powder into the liner inside a glovebox or under dry nitrogen flow to prevent moisture adsorption. - Level powder without compaction
Gently tap the liner to distribute the powder evenly; avoid pressing or tamping to maintain uniform thermal contact. - Set e-beam parameters for Nichrome
Program the e-beam power ramp to reach the 1,395 °C melting point gradually, monitoring for outgassing. - Monitor deposition rate stability
Observe the quartz crystal monitor for rate fluctuations; adjust beam sweep pattern if spitting occurs.
What evaporation method is recommended for Nichrome 99.95% powder and what source configuration is required?
E-beam evaporation is the preferred method, with performance rated as Excellent. The recommended source configuration for e-beam is a water-cooled hearth using an Al2O3 or graphite liner. Thermal or resistive evaporation is possible only by RFQ, with a W or Ta boat as the specified option.
What hearth liner and boat materials are compatible with this Nichrome evaporation material?
For e-beam evaporation, the product is designed for use with a water-cooled e-beam hearth lined with Al2O3 or graphite. For thermal evaporation via RFQ, tungsten (W) or tantalum (Ta) boats are listed as compatible. The product description explicitly specifies these materials for deposition-source matching.
What is the significance of the 99.95% purity specification and the 325 mesh powder form for this product?
The 99.95% purity identifies this as a high-purity research-grade alloy evaporation material, enabling direct comparison with standard and RFQ-controlled grades. The 325 mesh powder form is specified for vacuum thin-film deposition, and handling should follow the certificate and safety data sheet to maintain purity. Available pack sizes are 25g, 100g, 500g, and 1kg.
This Nichrome (Ni/Cr) evaporation material in 99.95% purity, 325 mesh powder form is optimized for e-beam evaporation using a water-cooled hearth with Al2O3/graphite liner, offering excellent performance for thin-film deposition, though thermal/resistive evaporation requires RFQ confirmation and boat compatibility must be verified.
Positive
- High-purity alloy powder for deposition: The 99.95% purity and 325 mesh powder form enable consistent source loading and controlled evaporation in vacuum thin-film workflows, with excellent performance in e-beam evaporation using a water-cooled hearth with Al2O3/graphite liner.
- Multiple pack sizes for lab scaling: Available in 25g, 100g, 500g, and 1kg packs, allowing researchers to match quantity to experimental or production needs without over-procurement.
Trade-offs
- Thermal evaporation requires RFQ: Thermal or resistive evaporation is not directly supported and requires RFQ confirmation, with boat compatibility limited to W or W/Ta materials, adding procurement lead time.
- Deposition hardware must be verified: Buyers must confirm deposition source geometry, liner material (Al2O3/graphite), and boat type before ordering to avoid incompatibility with existing vacuum systems.
