Silicon Carbide Graphite Crucible Overview

Our crucibles are made from a carefully selected blend of silicon carbide and natural graphite, ensuring superior performance in demanding casting environments. The materials we use are known for their:

  • High bulk density
  • Exceptional resistance to high temperatures
  • Corrosion resistance against acids and alkalis
  • Rapid thermal conduction
  • Minimal carbon emissions

These characteristics make our silicon carbide graphite crucibles a superior choice for aluminum casting, bronze casting, and other metal melting applications. Compared to conventional clay graphite crucibles, our crucibles are three to five times more durable, offering significant cost savings over time.

Key Features:

  • Rapid Thermal Conduction: The combination of highly conductive materials and dense structure ensures fast heat transfer, reducing energy consumption and increasing efficiency.
  • Extended Lifespan: Our crucibles can last 2 to 5 times longer than traditional clay graphite crucibles, providing greater value and reliability.
  • Unmatched Density: By utilizing isostatic pressing technology, we achieve uniform material density, which minimizes defects and enhances overall strength.
  • Exceptional Endurance: The incorporation of high-quality raw materials and optimized crucible recipes ensures our products can withstand extreme thermal conditions and mechanical stresses.
  • Oxidation Protection: The advanced formulation offers excellent oxidation resistance, even at high temperatures, ensuring your molten metals remain pure and uncontaminated.

FAQS

Q1: What are the advantages of silicon carbide graphite crucibles compared to traditional graphite crucibles?

✅ Higher Temperature Resistance: Can withstand 1800°C long-term and 2200°C short-term (vs. ≤1600°C for graphite).
✅ Longer Lifespan: 5x better thermal shock resistance, 3-5x longer average service life.
✅ Zero Contamination: No carbon penetration, ensuring molten metal purity.

Q2: Which metals can be melted in these crucibles?
▸ Common Metals: Aluminum, copper, zinc, gold, silver, etc.
▸ Reactive Metals: Lithium, sodium, calcium (requires Si₃N₄ coating).
▸ Refractory Metals: Tungsten, molybdenum, titanium (requires vacuum/inert gas).

Q3: Do new crucibles require pre-treatment before use?
Mandatory Baking: Slowly heat to 300°C → hold for 2 hours (removes residual moisture).
First Melt Recommendation: Melt a batch of scrap material first (forms a protective layer).

Q4: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).

Q5: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).

Q6: What is the minimum order quantity (MOQ)?

Standard Models: 1 piece (samples available).

Custom Designs: 10 pieces (CAD drawings required).

Q7: What is the lead time?
⏳ In-Stock Items: Ships within 48 hours.
⏳ Custom Orders: 15-25 days for production and 20 days for mould.

Q8: How to determine if a crucible has failed?

Cracks > 5mm on inner wall.

Metal penetration depth > 2mm.

Deformation > 3% (measure outer diameter change).

Q9: Do you provide melting process guidance?

Heating curves for different metals.

Inert gas flow rate calculator.
