Cell Lab 3N5 (99.95%) Niobium (Nb) Pellets Evaporation Materials [2 mm Dia × 5–8 mm L]

High-Purity Niobium for Thin-Film, Superconducting, and Coating Applications

General Description

Cell Lab 3N5 (99.95%) Niobium (Nb) Pellets are premium-quality evaporation materials engineered for vacuum coating, superconducting, and surface protection applications. Niobium is a light-grey, ductile transition metal known for its high melting point, superior oxidation resistance, and excellent biocompatibility — making it ideal for metal-based transistors, implant coatings, and high-strength alloy production.

In thin-film research, niobium is frequently used in superconducting films, optical coatings, and protective layers on electronic and medical substrates. Beyond research, it plays a crucial role in pipeline steel, welding electrodes, aerospace alloys, and nuclear components.

Key Features

  • High Purity (99.95%) – Ensures minimal impurities for reliable electronic and vacuum coating performance.

  • Excellent Oxidation Resistance – Forms stable Nb₂O₅ layers at elevated temperatures.

  • Superconductive Properties – Suitable for applications in quantum devices and cryogenic systems.

  • Biocompatible Surface – Used for biomedical coatings and corrosion-resistant implants.

  • Customisable Dimensions – Standard 2 mm × 5–8 mm pellets; other dimensions available upon request.

FAQ

Q1: What makes Niobium suitable for superconducting thin films?
Niobium’s low resistivity and high critical temperature (Tc ≈ 9.2 K) make it an ideal superconductor for quantum and cryogenic applications.

Q2: Can Niobium be co-evaporated with other metals?
Yes. It is commonly co-evaporated with Ti, Al, or Nb₂O₅ to create multilayer films or improve adhesion on substrates.

Q3: What are the main precautions when evaporating Niobium?
Maintain high-vacuum conditions and use refractory crucible liners (such as graphite or tungsten) to prevent contamination.

Q4: Is Niobium biocompatible for medical coatings?
Yes. Niobium coatings are non-toxic, corrosion-resistant, and frequently used on surgical and dental implants.
