Overview of 99.9% metals basis Ta Tantalum Metal Powder
99.9% metals basis Ta Tantalum Metal Powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of 99.9% metals basis Ta Tantalum Metal Powder
-
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 99.9% metals basis Ta Tantalum Metal Powder
Tantalum (Ta) metal powder, with a purity level of 99.9% (often referred to as 4N or 99.999% pure), has several key parameters that define its properties and characteristics. Here’s a breakdown of some important parameters:
1. **Purity**: As mentioned, the purity is 99.9% (4N) tantalum, indicating that less than 0.1% impurities are present.
2. **Particle Size Distribution**: This refers to the range of particle sizes in the powder. It is typically specified in terms of average diameter (D50, D90, etc.) or a size distribution curve. For high-purity tantalum, the particle size is usually controlled to ensure uniformity for specific applications.
3. **Density**: Tantalum has a high density, around 16.65 g/cm³, which contributes to its strength and stability.
4. **Melting Point**: The melting point of pure tantalum is 3017°C (5457°F), making it a refractory material with excellent heat resistance.
5. **Mechanical Properties**: High-purity tantalum powder generally exhibits good mechanical strength, hardness, and ductility, although these properties may vary depending on the processing method.
6. **Surface Finish**: The surface finish of the powder can be various, such as milled, ball-milled, or electrochemically etched, which affects the powder’s flowability and sintering properties.
7. **Chemical Stability**: Tantalum is chemically inert and resistant to corrosion, which makes it suitable for use in harsh environments.
8. **Sinterability**: The ability of the powder to form a dense, solid structure when compacted and heated (sintering process) is influenced by factors like particle size, shape, and composition.
9. **Electrical Conductivity**: Tantalum is a good electrical conductor, with a high electrical conductivity similar to copper.
10. **Thermal Conductivity**: Tantalum has excellent thermal conductivity, which is useful in applications where heat dissipation is critical.
These parameters can vary slightly between different suppliers, so it’s essential to consult the specific product data sheet for detailed information on a particular tantalum metal powder batch.
