Features of tantalum evaporation material Tantalum Lump Ta coating particles 99.95% tantalum granules
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of tantalum evaporation material Tantalum Lump Ta coating particles 99.95% tantalum granules
Tantalum, a chemical element with the symbol Ta and atomic number 73, is a highly sought-after metal due to its exceptional properties, such as high melting point, corrosion resistance, and stability in extreme conditions. Among various tantalum materials, tantalum lumps, tantalum coating particles, and 99.95% pure tantalum granules are some of the key forms utilized in various industries.
Tantalum lumps, also known as tantalum shot or tantalum ingots, are raw materials that consist of irregularly shaped pieces of pure tantalum. These lumps are typically obtained through refining processes, starting from tantalite ore, which is the most common source of tantalum. The purity of these lumps can range from 99.5% to 99.95%, with the higher purity grade being suitable for applications requiring minimal contamination.
Tantalum coating particles, on the other hand, are engineered for specific surface treatments and coatings. They are often produced by atomization or milling techniques, where tantalum ingots are into fine particles. These particles have a uniform size distribution, ensuring consistent and efficient deposition during coating processes. They find applications in semiconductor manufacturing, where they provide thin, durable layers that protect electronic components from corrosion and wear.
99.95% tantalum granules, also referred to as micro-tantalum beads or powder, are extremely pure and consist of small, spherical tantalum particles. This form is particularly useful in applications where high purity is critical, such as in chemical reactors, medical implants, and precision instruments. The ultra-fine particles enable precise control over the material’s distribution, making it ideal for sputtering processes or as a catalyst support.
The manufacturing process for these tantalum products begins with the extraction of tantalite ore, followed by beneficiation, smelting, and purification. The refining steps involve converting tantalite into tantalum pentoxide, which is then reduced to metallic tantalum. The purity of the final product is achieved through electrolysis or other refining methods.
In summary, tantalum lumps, coating particles, and 99.95% tantalum granules are versatile materials with unique properties that make them indispensable in various industries. Their high melting point, corrosion resistance, and stability make them suitable for applications ranging from aerospace to electronics, medical devices, and more. The manufacturing process, while complex, ensures the production of high-quality tantalum products that meet strict purity standards and performance requirements.
