Silicon crucible

Key Features of Silicon Crucibles

• Low Coefficient of Thermal Expansion: Silicon crucibles are engineered to resist thermal shock, reducing the risk of cracking when exposed to sudden temperature changes.
• High Corrosion Resistance: These crucibles maintain chemical stability even at high temperatures, preventing unwanted reactions during the smelting process. This is crucial in ensuring the purity of the molten metal.
• Smooth Inner Walls: The inner surface of silicon crucibles is smooth, reducing metal adhesion. This results in better pourability and minimizes the risk of leaks.
• Energy Efficiency: Their excellent thermal conductivity allows for fast melting, reducing energy consumption and operational costs, especially when used in gas-fired and induction furnaces.

Applications of Silicon Crucibles

Silicon crucibles are widely used in industries where precision and reliability are paramount:

• Foundries: For melting aluminum, copper, and their alloys. The smooth pourability and durability of silicon crucibles make them ideal for high-volume operations.
• Precious Metal Refining: These crucibles can withstand the high temperatures required for melting gold, silver, and other precious metals, ensuring purity and minimizing losses during the process.
• Induction Furnaces: They are specifically designed to handle the electromagnetic fields generated by induction furnaces, providing excellent heating performance without overheating.
