Key Characteristics of Factory direct pure precious metal gold nano powder 20nm-1um, gold nanopowder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Factory direct pure precious metal gold nano powder 20nm-1um, gold nanopowder
Gold nano powder, also known as gold nanoparticles, are highly sought-after materials due to their unique properties, such as enhanced chemical reactivity and optical characteristics compared to bulk gold. The Factory Direct Pure Precious Metal Gold Nano Powder with a size range of 20nm to 1um (nanometers) typically has the following parameters:
1. **Particle Size Distribution**:
– Average diameter: 20-1000 nanometers (20nm to 1 micron)
– Size dispersity: narrow or broad, depending on the manufacturing process (typically <10% for high-quality products)
2. **Purity**:
– 99.99% pure gold (24K or higher), ensuring minimal impurities
3. **Shape**:
– Generally spherical or near-spherical, although some processes may result in anisotropic shapes like rods or cubes (size-dependent)
4. **Surface Area**:
– Increased surface area due to the nanoscale dimensions, which can range from several hundred to thousands of square meters per gram (specific value depends on particle size)
5. **Density**:
– Similar to bulk gold (19.3 g/cm³)
6. **Crystal Structure**:
– Face-centered cubic (FCC) structure, common for gold nanoparticles
7. **Colloidal Stability**:
– Stable in various solvents, often dispersed in water or organic solvents with stabilizing agents (e.g., surfactants or polymers)
8. **Optical Properties**:
– Plasmonic properties, which exhibit unique colors due to surface plasmon resonance (SPR) – depending on the size and shape, these can be in the visible or near-infrared spectrum
9. **Electronic Properties**:
– Quantum confinement effects, leading to size-dependent electronic behavior (e.g., enhanced electrical conductivity)
10. **Safety and Toxicity**:
– Depending on the application, it's important to consider the toxicity level; gold is generally considered biocompatible, but specific batches may require further testing.
These parameters may vary slightly between manufacturers, so it's essential to check the product specifications provided by the supplier for accurate information.
