Sic Crucibles
Introduction to Sic Crucibles
Physical and Chemical Properties of Sic Crucibles
When selecting crucibles for industrial applications, understanding the physical and chemical indexes is critical. Below is a breakdown of the key properties of ISO Type Sic Crucibles:
| Physical Properties | Index |
|---|---|
| Refractoriness | ≥ 1650°C |
| Apparent Porosity | ≤ 20% |
| Bulk Density | ≥ 2.2 g/cm² |
| Crushing Strength | ≥ 8.5 MPa |
| Chemical Composition | Index |
|---|---|
| Carbon Content (C%) | 20–30% |
| Silicon Carbide (SiC%) | 50–60% |
| Alumina (AL2O3%) | 3–5% |
These characteristics give Sic Crucibles exceptional thermal conductivity, low thermal expansion, and resistance to chemical corrosion, ensuring that they perform efficiently in even the harshest environments.

Advantages of Sic Crucibles
- High-Temperature Resistance: Sic Crucibles withstand temperatures up to 1650°C, making them ideal for metal melting and other high-heat applications.
- Durability and Longevity: With a strong crushing strength of ≥ 8.5 MPa, these crucibles can endure the mechanical stresses involved in industrial settings without cracking or deforming.
- Chemical Stability: The high silicon carbide content (50-60%) offers excellent resistance to chemical reactions, ensuring longevity even when exposed to molten metals or aggressive chemicals.
Safe Handling and Maintenance of Sic Crucibles
To extend the lifespan of Sic Crucibles and ensure their safe operation, it is essential to follow a few maintenance guidelines:
- Regular Cleaning: Crucibles should be cleaned regularly to remove any residue, preventing contamination and corrosion.
- Avoid Thermal Shock: Gradual heating and cooling are essential to prevent cracking. Sudden temperature changes can cause the material to fracture.
- Prevent Chemical Corrosion: Avoid exposure to corrosive chemicals, especially alkaline or acidic solutions, which can degrade the crucible’s structural integrity.
Practical Knowledge for Buyers
Choosing the right Sic Crucible depends on the specific needs of your industrial process. Consider factors such as temperature, material compatibility, and size requirements. In real-world applications, many buyers have reported a significant reduction in maintenance costs and increased production efficiency by switching to Sic Crucibles.
Sic Crucibles are an indispensable tool for industries that demand high-performance materials capable of withstanding extreme temperatures and chemical exposure. By understanding their properties and following proper maintenance protocols, businesses can enhance operational efficiency while reducing downtime.
