High-Purity Ferromagnetic Material for Thin-Film and Battery Applications
Cell Lab 3N5 (99.95%) Cobalt (Co) Pellets are precision-engineered evaporation materials designed for vacuum deposition, magnetic thin-film coating, and energy research. Cobalt is a lustrous, hard, greyish metallic element known for its ferromagnetic behaviour, excellent thermal stability, and corrosion resistance.
Due to its ability to form strong magnetic alloys and stable thin films, cobalt is widely used in magnetic storage media, battery fabrication, and semiconductor coatings. Its high melting point of 1,495 °C and low vapour pressure characteristics make it ideal for controlled thermal and electron-beam evaporation processes.
High Purity (99.95%) – Ensures low contamination in precision coating and vacuum deposition systems.
Ferromagnetic Properties – Ideal for magnetic thin-film deposition and data storage technologies.
Thermal Stability – Maintains structure and conductivity at high operating temperatures.
Excellent Adhesion – Forms uniform, adherent coatings on a wide range of substrates.
Versatile Use – Suitable for evaporation, sputtering, and metallisation in electronic devices.

Q1: Why is cobalt preferred for magnetic film deposition?
Cobalt’s ferromagnetic nature and high Curie temperature make it essential for thin films requiring strong, stable magnetic properties.
Q2: What are the recommended crucible materials for evaporation?
Al₂O₃ crucibles or W/Nb boats provide excellent compatibility and temperature control.
Q3: Is cobalt suitable for co-evaporation processes?
Yes. It is frequently co-evaporated with nickel or platinum to produce multilayer magnetic or conductive coatings.
Q4: Can this material be used in semiconductor research?
Absolutely. Cobalt is widely used in interconnect metallisation and diffusion barrier layers in semiconductor fabrication.
