Copper Oxide (CuO) Nanopowder / Nanoparticles – 99%, 40 nm

Description

Copper Oxide (CuO) Nanopowder / Nanoparticles – 99%, 40 nm

Our Copper Oxide Nanopowder (CuO) features high purity (99%) and a fine particle size averaging 40 nm (TEM), with 80% of particles at 40 nm, 10% smaller, and 10% slightly larger, including a minimal fraction (~2%) reaching 80 nm. The powder exhibits a brown-black appearance, a high specific surface area (~45 m²/g), and a nearly spherical morphology. With a bulk density of 0.55 g/cm³ and a true density of 6.4 g/cm³, this nanomaterial is optimized for advanced material science and industrial applications.

Elemental Analysis (ppm)

Chemical Properties

Copper Oxide is insoluble in water but dissolves slowly in alcohol or ammonia solutions. It is soluble in dilute acids, ammonium chloride (NH₄Cl), ammonium carbonate ((NH₄)₂CO₃), and potassium cyanide solution. At elevated temperatures, it can be reduced to metallic copper by hydrogen or carbon monoxide.

Applications

Copper Oxide Nanopowder is widely used in:

• Catalysts: For combustion, chemical synthesis, and AP composite propellants (improving burn rate and lowering pressure index).

• Electronics: Ceramic resistors, gas sensors, magnetic storage media.

• Energy Applications: Thermoelectric and superconducting materials, solar energy transformation.

• Optics: Near-infrared filters, photoconductive and photothermal devices.

• Glass and Ceramics: As a functional additive for high-performance materials.
