Cell Lab 3N5 (99.95%) Magnesium Oxide (MgO) Pieces Evaporation Materials [1–3 mm]

High-Purity MgO for Thin-Film Deposition, Catalysis, and Battery Research

General Description

Cell Lab 3N5 (99.95%) Magnesium Oxide (MgO) Pieces are high-purity evaporation materials designed for vacuum coating, superconductor research, and catalytic applications. With its excellent thermal stability, chemical inertness, and high melting point (2,852 °C), MgO is a reliable choice for buffer layers, protective coatings, and battery electrode enhancement.

In thin-film technology, MgO is frequently used as a buffer layer between superconductors and substrates to improve lattice matching. It also serves as a corrosion-resistant and dielectric coating for Mg alloys and steels. Additionally, MgO contributes to the stability of cathode materials in Li-ion batteries under high-temperature operation.

Key Features

  • High Purity (99.95%) – Ensures low contamination and high reproducibility in deposition results.

  • Exceptional Thermal Resistance – Melting point up to 2,852 °C for use in extreme environments.

  • Excellent Chemical Stability – Insoluble in water, resistant to most solvents and reactive gases.

  • Versatile Applications – Used in superconductors, Li-ion battery research, and protective coatings.

  • Customisable Dimensions – Available in 50 g or 100 g packs; other sizes available upon request.

FAQ

Q1: Can MgO be evaporated directly under vacuum?
Yes. MgO can be evaporated thermally or via E-beam; using an oxygen-rich environment helps maintain stoichiometry.

Q2: What substrates are suitable for MgO coatings?
It adheres well to metal, glass, ceramic, and semiconductor substrates.

Q3: Is MgO hygroscopic?
Slightly. Store in a dry, sealed container to avoid moisture absorption.

Q4: Can Cell Lab customise MgO purity or particle size?
Yes. Custom purities (up to 99.999%) and granule sizes are available upon request.
