Product Overview
High-purity tungsten targets are made from pure tungsten powder through sintering and forging processes. Tungsten has an extremely high melting point (3410°C), density (19.3g/cm³), and other excellent physical properties, such as high elasticity, low expansion coefficient, and low vapor pressure. Tungsten targets offer high sputtering efficiency and excellent thermal and chemical stability, making them ideal for various applications, particularly in thin-film deposition industries.
Key Features
- High Melting Point: Tungsten's exceptionally high melting point allows it to withstand high-temperature environments, making it ideal for high-temperature processes.
- Low Expansion Coefficient: Suitable for applications that require precise control over shape and size.
- Thermal and Chemical Stability: Tungsten targets offer excellent corrosion resistance and oxidation resistance, making them ideal for harsh working conditions.
- Low Vapor Pressure: Tungsten maintains stable physical properties at high temperatures, ideal for high-precision sputtering applications.
Applications
Tungsten targets are widely used in multiple industries, particularly for thin-film deposition:
- Thin-Film Coating: Commonly used in optical coatings, CD-ROM manufacturing, decorative coatings, etc.
- Display Manufacturing: Used for functional layer coatings in flat-panel display production.
- Optical Information Storage: Applied in optical communications and other high-performance optical information storage applications.
- Glass Coatings: Tungsten targets are used in automotive and architectural glass coating to enhance durability and optical performance.
- Optoelectronics: Used in other high-precision devices to improve optical and electronic performance.
