Technical & Application Notes

1. A Model System for Hydrogen Storage and Reactive Thin Films

The CeMg intermetallic compound is a classic system studied for its hydrogen absorption properties. When sputtered as a thin film, it can serve as a model layer for investigating hydriding kinetics, hydrogen storage capacity, and the effects of nanostructuring at the nanoscale—a critical area for future energy technologies.

2. Challenges and Expertise in Fabrication

Producing a homogeneous CeMg target is challenging due to the significant difference in vapor pressure and reactivity between Ce (highly reactive rare earth) and Mg (volatile). SAM employs specialized arc melting under inert atmosphere or powder metallurgy with sealed sintering to achieve a uniform, single-phase intermetallic compound, ensuring consistent composition in the sputtered flux.

3. Primary Research & Development Applications

• Hydrogen Storage & Sensor Materials: For fundamental research on thin-film hydrides, where the well-defined CeMg phase allows precise study of hydrogen absorption/desorption mechanisms.
• Corrosion-Resistant Coatings: Magnesium alloys often benefit from rare earth additions for improved corrosion resistance. CeMg films or coatings derived from it may offer unique protective properties for light-weight alloys.
• Optical & Functional Coatings: Rare earth elements like Ce can influence optical properties. CeMg or its oxides/nitrides (via reactive sputtering) may be explored for selective solar absorbers or other functional optical coatings.
• Fundamental Materials Science: As a model intermetallic system for studying phase stability, oxidation behavior, and thin-film growth dynamics of reactive metal compounds.

Quality Assurance

Given the reactive nature of the constituents, targets are handled and packaged in inert environments. Composition is verified using Inductively Coupled Plasma (ICP) analysis. X-ray Diffraction (XRD) is used to confirm the formation of the desired CeMg intermetallic phase and assess phase purity. These data are included in the provided CoA.
