Features of CAS 12070-06-3 High Purity 99.5% TaC Powder for Ceramics Tantalum Carbide
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 CAS 12070-06-3 High Purity 99.5% TaC Powder for Ceramics Tantalum Carbide
Tantalum carbide (TaC), with the chemical formula CAS No. 12070-06-3, is a high-performance ceramic material known for its exceptional properties, particularly in extreme environments and applications where wear resistance, thermal stability, and electrical conductivity are paramount. It boasts a purity level of 99.5%, ensuring a consistently reliable performance.
TaC powder, when used in ceramics, plays a crucial role due to its unique structure. It consists of tantalum atoms bonded with carbon atoms in a hexagonal lattice, forming a hard, metallic-like phase. This structure gives it outstanding hardness, higher than that of diamond, making it an ideal material for applications requiring durability and resistance. In cutting tools, wear-resistant coatings, and mechanical components, TaC significantly extends tool life and improves efficiency.
The high thermal stability of TaC makes it suitable for use in high-temperature applications, such as in aerospace, where exposure to elevated temperatures is common. It maintains its integrity even under severe heat conditions, minimizing deformation and ensuring reliable performance over time. Additionally, TaC’s low thermal expansion coefficient reduces the risk of thermal stress and cracking, further enhancing its durability.
From an electrical perspective, TaC is a semi-metallic compound that exhibits good electrical conductivity, which is particularly attractive for electronic applications. It is often employed in contacts, switches, and heat sinks where high current density and low resistance are required. The combination of high thermal conductivity and electrical conductivity makes TaC a sought-after material for power electronics and microelectronics.
In the field of ceramic engineering, TaC powder is processed into various shapes and forms, such as powders, sintered bodies, or composite materials, through techniques like hot pressing, spark plasma sintering, or chemical vapor deposition. These processes allow for precise control over the final product’s properties, ensuring they meet specific requirements for various industries.
Due to its inherent advantages, TaC finds applications in diverse sectors, including automotive, energy, defense, and medical equipment. For instance, in the automotive industry, it is used in brake systems and bearings, where its wear resistance reduces maintenance costs. In the energy sector, TaC is employed in high-temperature turbine blades, contributing to enhanced engine efficiency. In the defense industry, it is utilized for armor-piercing penetrators and as a coating for lightweight, yet durable, components.
In summary, CAS 12070-06-3 high purity TaC powder is a versatile and robust material that stands out for its exceptional wear resistance, thermal stability, and electrical conductivity. Its widespread application in ceramics underscores its importance in modern technology and engineering, enabling innovation across various industries that demand performance under challenging conditions.
