Description

Tantalum Carbide CAS NO 12070-07-4 is an extremely hard, refractory ceramic material composed of tantalum and carbon. It is a critical component in the production of ultra-high-temperature structural materials and wear-resistant coatings, valued for its exceptional thermal stability and chemical inertness. This advanced ceramic is essential for manufacturers in the aerospace, defense, and cutting tool industries, where performance under extreme conditions is paramount.

Application

• Cutting Tools & Inserts: As a key constituent in cemented carbides (cermets) to enhance hardness, wear resistance, and high-temperature machining performance.
• Aerospace Components: Used in thermal protection systems, rocket nozzles, and leading-edge components for hypersonic vehicles due to its ultra-high melting point.
• Protective Coatings: Applied via CVD or PVD processes to create wear- and corrosion-resistant surfaces on critical industrial parts.
• Refractory Materials: Incorporated into linings for high-temperature furnaces and reactors in metallurgical and chemical processing.
• Hard Alloy Additive: Serves as a grain growth inhibitor and strengthening phase in tungsten carbide-cobalt (WC-Co) composites.
• Electronic Components: Utilized in thin-film resistors and as a diffusion barrier in microelectronics.

Quality Control

Our Tantalum Carbide is manufactured under controlled conditions and subjected to rigorous quality testing to ensure batch-to-batch consistency and compliance with technical-grade specifications. Key parameters such as purity, particle size distribution, and oxygen content are strictly monitored. A Certificate of Analysis (COA) detailing all test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). The product is stable under normal storage conditions but should be kept away from strong acids and strong oxidizing agents. Minimize exposure to moisture to prevent caking.
