Stanford Advanced Materials (SAM) manufactures various tungsten crucibles and other Tungsten parts such as tungsten heaters, heat insulation screens, tungsten sheets, supports, etc. We provide tailor-made products according to your drawings and specific requirements.


Product Overview

Tungsten is renowned for its durability and resistance to high temperatures and corrosion, particularly against molten metals and metal oxides. This makes it ideal for a range of demanding industrial applications. Our tungsten crucibles, especially those produced by Chemical Vapor Deposition (CVD), exhibit exceptional properties:

  • Density: Up to 98.5% of theoretical
  • Purity: Up to 99.9999%
  • Microstructure: Features a columnar or multilayer columnar crystal structure

Features & Applications


  • High Temperature Resistance: Effective operation at temperatures up to 2400°C, ideal for environments requiring extreme heat.
  • Corrosion Resistance: Offers outstanding resistance to corrosion from molten metals and oxides.
  • Low Contamination: Ensures minimal contamination in processes such as crystal growth and rare-earth melting.


Tungsten crucibles are extensively used in the growth of monocrystals from molten corundum, in high-temperature furnace applications, electronics, and thermal vaporization processes. Their high melting points and low pollution properties make them particularly effective for:

  • Crystal Growth: Widely used in the production of monocrystals from molten corundum, particularly sapphire crystals.
  • Metallurgy and Alloy Production: Essential for melting and mixing high-temperature metals and alloys.
  • Electronics and Coating Processes: Utilized in thermal vapor deposition processes for electronics manufacturing.

Each tungsten crucible is meticulously packaged to ensure maximum protection during transport and storage. We use sturdy wooden crates for larger crucibles and robust cartons for smaller sets, ensuring that each item is securely immobilized and protected from any potential damage.


Q1: Why choose tungsten for crucibles?
A1: Tungsten’s high melting point and low thermal expansion rate make it ideal for maintaining integrity under extreme conditions.

Q2: Can I customize the dimensions of a tungsten crucible?
A2: Yes, we offer customization for both dimensions and shapes to suit your specific requirements.

Q3: What are the purity levels available for these crucibles?
A3: Our standard purity is ≥99.95%, but we can provide up to 99.999% purity for specialized applications.

Q4: How are tungsten crucibles packaged?
A4: Each crucible is securely packaged in a wooden crate to protect it during transportation. Smaller sets may be packaged in cartons.

Q5: How should I handle and maintain my tungsten crucible?
A5: To ensure longevity, avoid rapid temperature changes and mechanical shocks during use.
