Features of Low 99.9% Tantalum Metal Powder With CAS No.7440-25-7
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 Low 99.9% Tantalum Metal Powder With CAS No.7440-25-7
Tantalum metal powder, with the chemical symbol Ta and CAS number 7440-25-7, is a high-performance metallic material known for its exceptional properties that make it indispensable in various industries. This specific grade boasts a low 99.9% impurity level, ensuring a near-perfect purity that translates to superior performance and reliability.
Tantalum is a rare, hard, lustrous transition metal found naturally in the mineral tantalite. It is characterized by its high melting point, which stands at around 3,027 degrees Celsius (5,481 degrees Fahrenheit), making it one of the most heat-resistant materials. This feature makes tantalum ideal for applications where thermal stability is paramount, such as in high-temperature electronics and aerospace components.
The low 99.9% impurity content means that the powder contains less than 0.1% impurities, primarily consisting of trace elements like oxygen, nitrogen, and carbon. This level of purity is crucial for maintaining the material’s exceptional strength, ductility, and corrosion resistance. In applications like chemical processing, semiconductor fabrication, or medical implants, where contamination can compromise functionality or biocompatibility, the purity of tantalum powder is of utmost importance.
In terms of mechanical properties, tantalum is incredibly strong and tough, with a high yield strength and excellent wear resistance. It also possesses excellent fatigue resistance, meaning it can withstand repeated stress without degrading over time. This durability is why tantalum finds application in bearings, gears, and other precision components that require long-lasting performance.
Moreover, tantalum’s inherent non-reactivity with most chemicals and acids makes it an ideal choice for use in chemical processing equipment, particularly in harsh environments. It is also resistant to corrosion in both air and water, which extends the service life of components and reduces maintenance requirements.
In the field of electronics, tantalum capacitors, derived from this metal powder, are renowned for their stability and longevity. These capacitors are used in critical applications like military, telecommunications, and power supply systems due to their ability to maintain capacitance over extended periods without degradation.
The biomedical industry also appreciates tantalum’s biocompatibility, as it does not cause adverse reactions when implanted in the human body. It is used in orthopedic implants, dental crowns, and other medical devices where long-term contact with living tissue is required.
Lastly, tantalum’s unique combination of properties has led to its utilization in advanced technologies, such as nuclear reactors, where its high neutron cross-section and radiation resistance make it suitable for shielding and structural components.
In conclusion, the 99.9% pure tantalum metal powder with CAS number 7440-25-7 is a premium material characterized by its exceptional strength, heat resistance, and corrosion properties. Its low impurity level ensures optimal performance in diverse industries, ranging from aerospace and electronics to medicine and nuclear technology. As technology continues to advance, the demand for high-purity tantalum will likely remain strong, highlighting the material’s enduring value in modern engineering applications.
