Characteristics and Main Applications of Silicon Carbide Graphite Crucibles

1. Silicon carbide graphite crucibles are known for their unique characteristics and versatile applications. Here we present an introduction to their features and primary uses:
2. Fast Heat Conduction: Silicon carbide graphite crucibles utilize high thermal conductivity materials such as graphite, which reduces melting time and saves energy. The dense structure with low porosity further enhances heat conduction, resulting in rapid heating rates.
3. Long Lifespan: Compared to conventional clay graphite crucibles, the lifespan of silicon carbide graphite crucibles can be extended by 3-5 times, offering excellent durability and cost-effectiveness.
4. Strong Thermal Shock Resistance: These crucibles exhibit exceptional resistance to rapid temperature changes, making them highly resistant to cracking under thermal shock conditions. They can endure high thermal shock intensities, ensuring reliable performance in various heat treatment processes.
5. High Heat Resistance: Silicon carbide graphite crucibles exhibit exceptional temperature resistance, enabling them to withstand high temperatures without deformation or structural damage.
6. Corrosion Resistance: These crucibles demonstrate excellent resistance to corrosive molten materials. The average and dense matrix design delays corrosion, ensuring prolonged crucible lifespan.
7. Anti-Adhesion Properties: The non-stick nature of graphite minimizes metal adhesion to the crucible, reducing metal infiltration and minimizing residue build-up.
8. Minimal Metal Contamination: Strict control over material composition ensures that silicon carbide graphite crucibles do not contaminate the melted metal. The material design takes into consideration the relationship with the melted metal and process characteristics, effectively minimizing the introduction of harmful impurities.
9. Energy Efficiency and Environmental Friendliness: The fast heat conduction properties of these crucibles contribute to significant fuel savings and reduced exhaust emissions, promoting energy efficiency and environmental sustainability.
10. High Strength: Manufactured using high-quality materials and subjected to high-pressure molding, these crucibles exhibit excellent strength and resistance to cracking. They retain the various physical and chemical properties of natural graphite.
11. Oxidation Resistance: The crucibles are designed with superior oxidation resistance and utilize high-purity materials to protect the graphite structure. Their oxidation resistance is 5-10 times higher than that of conventional graphite crucibles.
12. Minimal Slag Adhesion: The inner walls of silicon carbide graphite crucibles have low slag adhesion, minimizing heat transfer resistance and the risk of crucible cracking. This ensures consistent and maximized capacity.
