High Purity Tantalum Crucible

Product Introduction

Tantalum crucibles are made of high-purity tantalum materials, which have excellent high temperature resistance, corrosion resistance and thermal conductivity. They are ideal containers for high-temperature melting, crystal growth and special material preparation. They are widely used in aerospace, semiconductors, optical glass and high-temperature alloys to meet the stringent needs of high-end industries.

High purity tantalum crucible Core advantages

Ultra-high temperature resistance: Tantalum has a melting point of up to 2996°C and can work stably in extremely high temperature environments.

Excellent corrosion resistance: It has strong corrosion resistance to acids, alkalis and molten metals and is suitable for a variety of chemical environments.

Excellent thermal conductivity: Ensures uniform heat distribution, improves smelting efficiency and material quality.

High-purity material: Tantalum purity ≥99.95%, avoids impurity contamination, and ensures high quality of smelting materials.

Long service life: Under suitable conditions, the service life far exceeds that of ordinary metal crucibles, reducing overall costs.

The High Purity Tantalum Crucible is an essential component in ultra-high temperature and corrosion-resistant industries. Known for its exceptional stability and chemical inertness, this product is widely used in vacuum coating, crystal growth, rare metal smelting, and semiconductor manufacturing.

Key Advantages:

• Outstanding Corrosion Resistance: Performs reliably in strong acids and alkalis, including HCl, H₂SO₄, and HF.
• Ultra-High Melting Point: Withstands temperatures above 3000°C without deformation or contamination.
• Excellent Thermal Conductivity: Ensures even heat distribution during melting and sintering.
• High Purity Stability: With purity levels up to 99.95%–99.99%, it prevents impurity diffusion and ensures product integrity.
• Ideal for Critical Applications: Perfect for aerospace, electronics, and vacuum furnace industries.

The High Purity Tantalum Crucible is especially valued by research institutions and industrial users who require reliable performance in extreme environments.

Be used in a wide range of industries.

Manufacturing & Process Flow

Our high purity tantalum crucibles are produced through precise metallurgical processes to ensure superior mechanical performance and surface finish.

Typical Process Flow:

1. Raw Material Selection: Premium-grade tantalum powder (≥99.95%) is sourced from certified suppliers.
2. EB or VAR Melting: Electron Beam or Vacuum Arc Refining ensures high purity and dense structure.
3. Hot Forging & Rolling: Homogenization improves strength and grain uniformity.
4. Deep Drawing or Spinning: Forming into crucible shapes under controlled temperature and pressure.
5. Precision Machining: CNC finishing ensures dimensional accuracy and smooth inner surfaces.
6. Annealing & Cleaning: High-vacuum annealing removes internal stress and impurities.
7. Inspection & Packaging: 100% quality inspection before shipment.

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

Quality is the core of Shaanxi Chuanghui Daye’s production philosophy. Every High Purity Tantalum Crucible undergoes multi-stage testing to ensure chemical stability, microstructure uniformity, and mechanical precision.

Main Quality Tests Include:

• Chemical Composition Analysis (ICP-OES): Confirms tantalum content ≥99.95%.
• Ultrasonic Testing: Detects internal voids and inclusions.
• Microstructure Inspection: Ensures uniform grain size and homogeneity.
• Dimensional Accuracy Check: Precision up to ±0.02 mm.
• Surface Roughness Measurement: Ra ≤ 0.4 μm for high-vacuum use.

All inspection data are documented and provided with a Mill Test Certificate (MTC) upon shipment.
