Tantalum Nitride granules are high-purity materials used in various industrial applications, including electronics, ceramics, and thin film resistors. They are known for their excellent thermal stability, high melting point, and unique properties.
Product Overview
Tantalum nitride (TaN) granules are gray-black compounds of tantalum and nitrogen, with various phases ranging from Ta₂N to Ta₃N₅. Known for their high melting point, excellent chemical stability, and high-temperature resistance, TaN granules are widely used in high-tech industries. The material has a hexagonal crystal structure with a density of 14.3 g/cm³, allowing it to maintain stability even at elevated temperatures.
Features
- High melting point (approximately 3090°C), suitable for extreme temperature environments
- Excellent chemical stability and moisture resistance
- Black crystalline appearance, offering strong corrosion resistance
- Insoluble in water, ensuring stability in complex chemical reactions
Applications
- Integrated Circuit Manufacturing: Used to form diffusion barriers or "glue" layers between copper or other conductive metals, especially in BEOL (back-end-of-line) processes, providing efficient barrier properties
- Thin Film Resistors: TaN’s excellent moisture resistance makes it more durable than the passivated oxide film formed by nickel-chromium alloy resistors, widely used in thin film resistors for electronic devices
- High-Temperature Applications: Due to its outstanding high-temperature resistance, TaN is used to protect electronic components and other high-temperature materials in harsh environments
