Magnesium Carbonate (MgCO₃) Nanopowder / Nanoparticles (99+%, 10–70 nm)

Description

Magnesium Carbonate (MgCO₃) Nanopowder / Nanoparticles (99+%, 10–70 nm)

Magnesium Carbonate (MgCO₃) Nanopowder is a high-purity white nanomaterial (99+%) with a particle size range of 10–70 nm. Owing to its large surface area, chemical stability, and non-toxic nature, it finds use across diverse industries such as cosmetics, fireproofing, food, and pharmaceuticals.

At the nanoscale, Magnesium Carbonate demonstrates enhanced reactivity and dispersion, making it an excellent functional filler in polymers, coatings, and construction materials. Its lightweight structure, combined with chemical inertness, also makes it valuable in specialized fire-safety and biomedical applications.
