Product Overview
Tantalum frustum is a high-performance, high-temperature-resistant container made from high-purity tantalum. Known for its excellent resistance to deformation and high-temperature stability, tantalum is a metal with an exceptionally high melting point, low vapor pressure, and superior cold-working and chemical stability. Tantalum frustums are widely used in high-temperature and corrosive environments, particularly in metallurgy, chemical, and electronics industries.
Features
- Excellent temperature resistance, suitable for extreme temperature conditions
- Exceptional corrosion resistance, particularly against molten metals and chemicals
- Outstanding cold-working properties and high dielectric constant of surface oxide film
- High-purity tantalum ensures stable and reliable performance
Applications
- Rare Earth Smelting: Tantalum frustums are used in the rare earth element smelting process, where high-temperature and corrosion resistance are critical for complex chemical reactions
- High-Temperature Sintering: Used as an anode carrier to maintain the stability and efficiency of electrolytic capacitors during high-temperature sintering
- Chemical Industry: Tantalum frustums serve as corrosion-resistant containers for storing and processing various corrosive chemicals
- Sputtering and Vapor Deposition: Provide a stable platform for reactions during surface modification, ensuring clean and stable surfaces
