Key Features of Our Silicon Carbide Crucibles

1. Materials and Composition:
   • Our Silicon Carbide Crucibles are crafted using high-quality silicon carbide bonding techniques. The carbon bonding process enhances the crucible's structural integrity, making them ideal for high-temperature applications.
   • The integration of silicon carbide clay and silicon carbide graphite ensures excellent thermal conductivity and durability, making them suitable for various melting processes.
2. Preheating Steps:
   • Proper preheating of the Silicon Carbide Crucible is essential to prevent issues such as thermal expansion, detachment, delamination, or cracking caused by residual moisture. Here’s how you can effectively prepare your crucibles:
     • First Baking: Bake the crucible in an oven without materials for over 24 hours, regularly rotating it to ensure even heating and moisture removal.
     • Gradual Heating: Preheat to 150-200°C for 1 hour, then increase the temperature at a rate of 150°C per hour, avoiding prolonged exposure to temperatures between 315-650°C to prevent oxidation.
     • High-Temperature Treatment: After the initial preheating, rapidly increase the temperature to 850-950°C for 30 minutes before adding materials. This treatment significantly extends the crucible's service life.
3. Specifications (Customizable):
   • Our Silicon Carbide Crucibles can be customized in size and dimensions to fit your specific melting requirements. Consult with us for tailored solutions that meet your production needs.
