Product Overview
Tungsten crucibles are high-temperature containers made from high-purity tungsten, widely used in high-temperature experiments and metallurgical processes. With a melting point of 3422°C, tungsten crucibles exhibit exceptional high-temperature and corrosion resistance, making them suitable for extreme conditions. Made from high-purity tungsten powder (FW-1 material) and precision-manufactured, these crucibles can maintain stability in vacuum or inert gas environments. They are commonly used in rare earth metal smelting, quartz glass melting, and other high-temperature processes.
Key Features
- High Purity Material: Made from tungsten with 99.9% purity (3N5) or higher, ensuring stability and corrosion resistance at high temperatures.
- Excellent High-Temperature Resistance: Tungsten crucibles can be used for extended periods in vacuum or inert gas environments at temperatures below 2600°C, making them ideal for extreme high-temperature applications.
- Customizable Shapes and Sizes: Tungsten crucibles can be customized in various sizes and shapes, including standard round, rectangular, and boat-shaped crucibles, based on customer requirements.
- Precision Manufacturing: Manufactured using sintering, stamping, and spinning techniques, ensuring high precision and quality.
Applications
Tungsten crucibles are widely used in various high-temperature and corrosion-resistant applications, including:
- Rare Earth Metal Smelting: Used extensively in the smelting of rare earth metals and high-temperature alloys due to their superior high-temperature and corrosion resistance properties.
- Induction Furnace Heating Elements: Tungsten crucibles can be used as heating elements in high-temperature induction furnaces, ideal for experiments and processes requiring extremely high temperatures.
- Quartz Glass Melting: Commonly used in the melting and processing of quartz glass, tungsten crucibles can withstand high temperatures and are resistant to chemical reactions.
- High-Temperature Containers: Tungsten crucibles also serve as high-temperature containers for other industrial applications that require materials with excellent heat and corrosion resistance.
