NanoIron(III) Oxide (Fe2O3) for Functional Color Coatings

itself is a common inorganic pigment (iron red color), and its color properties become even more superior after nanoscale processing.

 

Mechanism of action:

High tinting and covering power: Nanoparticles possess a larger specific surface area and higher surface activity, resulting in significantly superior tinting and covering power compared to micron-sized pigments, requiring less usage for better performance.

Transparent Coloring: By controlling particle size and distribution, transparent iron oxide pigments can be produced, suitable for applications such as metal-flake paint and wood varnish. These pigments not only reveal the texture or metallic luster of the substrate but also impart rich colors.

Color stability: Inorganic pigments inherently possess excellent resistance to heat, light, and chemicals, ensuring long-lasting and unchanging color.

 

Typical Application Case:

High-end automotive metallic paint/mica paint: Utilizing transparent nano-iron oxide red, combined with aluminum powder or mica pearlescent powder, to create a multi-layered and deep color effect.

Outdoor High-Performance Color Steel Plate Coating: Long-lasting vibrant colors with strong weather resistance.

Artistic coatings and cultural heritage preservation coatings: Utilizing their stable colors and chemical inertness.

Hollow silicon nano powder

Hollow nano silicon(Si) powder is a nanomaterial with unique structures and excellent properties, their hollow structures endow them with many special properties that are different from ordinary solid silicon powders.

Performance features of nano hollow Si particles:
1. Low density: Due to its hollow internal structure, the density of nano hollow silicon powder is significantly lower than that of solid Si powders, which makes it have important application value in fields where weight reduction is required, such as the preparation of lightweight materials in the aerospace field.
2. High SSA: The nano scale particle size and hollow structure endow it with a large specific surface area, which can provide more active sites and enable it to exhibit excellent performance in catalysis, adsorption and etc..
3.Good chemical stability: Silicon itself has good chemical stability, and nano hollow silicon particle also inherits this characteristic to a certain extent. It can remain stable in relatively harsh chemical environments and is less likely to undergo chemical reactions with other substances.

4. Unique optical properties: Its hollow structure has a special influence on the propagation and scattering of light, and may exhibit some unique optical properties, such as light scattering and absorption, which have potential application prospects in the fields of optical devices and sensors.

Currenly hollow Si powder is mainly used in the fields of:

1.Catalyst carrier: The high specific surface area and rich pore structure provide a large number of attachment sites for the catalyst, which can enhance the activity and selectivity of the catalyst. It is widely used in catalytic reactions in fields such as petrochemicals and environmental protection.

2. Anode material for lithium-ion batteries: Nano hollow silicon powder can effectively alleviate the volume expansion problem of silicon during charging and discharging, improve the cycle stability and charging and discharging performance of batteries, and is expected to become the anode material for the next generation of high-energy-density lithium-ion batteries.

3. Sustained drug release: It can serve as a drug carrier, encapsulating the drug within a hollow structure to achieve slow drug release, enhancing drug efficacy and reducing the frequency of administration.
