Thorium Oxide Tm2O3 Powder 99.99% 325 Mesh ATOMFAIR®

Thorium oxide powder requires controlled atmosphere storage to prevent moisture uptake and particle agglomeration. Deposition source compatibility must be verified against the specified liner or boat materials to avoid chemical attack or contamination.

• Moisture Sensitivity: Store powder in sealed containers under dry inert gas to prevent hygroscopic degradation and maintain flow properties.
• Source Compatibility: Use only graphite, alumina, or boron nitride liners for e-beam evaporation to avoid reactive wetting or crucible failure.
• Particle Size Constraint: The 325 mesh powder must be loaded without compaction to ensure uniform evaporation rate and avoid spitting.

This procedure covers safe loading of thorium oxide powder into an e-beam hearth and execution of evaporation for thin-film deposition. Verify source geometry and liner material before beginning the process.

Required Equipment: E-beam evaporation system with graphite/Al2O3/BN liner, Inert gas glovebox or dry nitrogen purge station, Stainless steel spatula or ceramic scoop

1. Prepare the powder
   Transfer the required mass of thorium oxide powder from the sealed container into a clean ceramic crucible inside a dry inert atmosphere.
2. Load the hearth liner
   Fill the e-beam hearth liner with powder to no more than 70% of its volume, tapping gently to level without compacting.
3. Pump down the chamber
   Evacuate the deposition chamber to a base pressure below 5e-6 Torr before initiating any heating sequence.
4. Outgas the material
   Ramp the e-beam power slowly to 30% of target while monitoring chamber pressure for sudden rises indicating trapped gas release.
5. Evaporate the film
   Increase beam power to achieve a stable deposition rate of 0.5–2 Å/s as measured by quartz crystal monitor.

Thorium Oxide (Tm2O3) evaporation material, 99.99% purity, 325 mesh powder, is evaluated for e-beam evaporation with specific hearth liner or boat requirements, offering defined material identity and particle sizing for thin-film deposition, but requiring careful source compatibility and handling due to its radioactive nature.

Positive

• High purity and defined particle size: 99.99% purity and 325 mesh powder form ensure consistent evaporation behavior and film quality, enabling precise procurement matching for research-grade thin-film deposition.
• Flexible pack size options: Available in 25g, 100g, 500g, and 1kg packs, allowing laboratories to scale material quantity to experimental needs without excess waste.

Trade-offs

• Specialized deposition hardware required: E-beam evaporation is preferred, requiring a hearth with graphite, Al2O3, or BN liner, or W/Mo/Ta boat; thermal evaporation requires RFQ, limiting direct compatibility with standard thermal sources.
• Radioactive material handling constraints: Thorium oxide is radioactive, necessitating safety data sheet review, export controls, and specialized laboratory handling procedures, which may increase procurement and operational complexity.
