Tungsten Crucible

Product Introduction

The high-performance crucible from Shaanxi Chuanghui Daye Metal Material Co., Ltd. is precision-engineered using ultra-high-purity tungsten, making it ideal for extreme operating conditions. It offers outstanding thermal conductivity, excellent chemical stability, and superior mechanical strength at elevated temperatures. Manufactured to meet strict international standards, this product is suitable for applications in metallurgy, electronics, semiconductors, vacuum systems, and laboratory research.

Thanks to tungsten’s exceptionally high melting point of around 3422°C, the crucible can endure prolonged exposure to intense heat without warping or chemical degradation. It is particularly well-suited for high-temperature metal melting, vacuum furnace operations, and semiconductor processing where thermal stability and contamination-free conditions are crucial.

Tungsten’s unique properties—such as high melting point, corrosion and wear resistance, and a low coefficient of thermal expansion—make it widely used in sapphire single crystal growth, quartz glass melting, rare-earth material processing, and electronic deposition applications.

Description

Grade : W1

Application : Used for sapphire crystal growing, rare earth metal metallurgy.

Product Features:

Excellent high temperature resistance: can be used in high temperature melting and other processes, such as in the melting of some rare metals (such as tantalum, niobium), can withstand the high temperature required for the melting of these metals, to ensure the smooth melting process. - Strong corrosion resistance: In some high temperature scenarios where the corrosive environment is relatively weak, tungsten crucible can maintain good stability, thereby extending the service life. - High thermal conductivity: Tungsten has a high thermal conductivity and can quickly and evenly conduct heat, which is conducive to uniform heating of the material in the crucible, which is very important in metal melting or high-temperature chemical reactions.

Manufacturing & Process Flow

The production of the Tungsten Crucible follows a meticulously controlled process to guarantee high quality and consistency. The main steps include:

1. High-Purity Tungsten Powder Selection: Only premium-grade tungsten powder is selected to ensure chemical purity and consistent microstructure.
2. Powder Compaction and Sintering: Tungsten powder is compacted under high pressure and sintered in vacuum or inert atmospheres to create dense, uniform structures.
3. Hot Pressing & Forging: To enhance mechanical strength, sintered blanks undergo hot pressing and forging under controlled conditions.
4. Precision Machining: Using advanced CNC machines and electron beam furnaces, the crucibles are precisely machined to meet tight dimensional tolerances.
5. Surface Treatment: Final polishing and cleaning processes remove surface impurities, ensuring a smooth finish suitable for high-purity applications.
6. Quality Checks Throughout: In-process inspections are carried out to monitor density, dimensions, and surface quality, guaranteeing that each crucible meets our strict standards.

​​​​Quality Control & Inspection​​​​​​​​​​​​​​

Quality assurance is a cornerstone of Shaanxi Chuanghui Daye’s manufacturing philosophy. The Tungsten Crucible undergoes rigorous inspection procedures, including:

• Chemical Composition Verification: Ensuring that the tungsten content is above 99.95% and free of contaminants.
• Dimensional Accuracy Checks: Each crucible is measured using precision instruments to ensure adherence to design specifications.
• Density & Porosity Testing: High-density crucibles with minimal porosity are critical for thermal performance and structural integrity.
• High-Temperature Performance Evaluation: Crucibles are tested under extreme temperatures to verify thermal stability and resistance to deformation.
• Surface Integrity Assessment: Polished and finished surfaces are inspected to avoid micro-cracks or irregularities that could affect high-purity applications.
