Silicon Carbide Crucibles
Across International Silicon Carbide Crucibles offer efficient heat transfer and excellent thermal shock resistance for metal melting and holding applications. Their durable refractory construction supports repeated heating cycles, while resistance to chemical attack and erosion helps maintain reliable performance in compatible processes.
Key Features
High Thermal Conductivity – Promotes efficient heat transfer for rapid, consistent heating.
Thermal Shock Resistance – Helps withstand temperature changes during heating and cooling cycles.
Durable Construction – Provides mechanical strength for demanding laboratory and foundry applications.
Chemical and Erosion Resistance – Helps reduce deterioration when used with compatible metals and processing materials.
Versatile Applications – Suitable grades can be selected for aluminium, copper alloys, brass and precious-metal processing.
Select the crucible grade and size to suit the metal, furnace type, operating temperature and flux chemistry. Follow the recommended preheating and handling procedures to maximise service life.
Silicon carbide crucibles heat resistant graphite crucible with flat bottom. Maximum casting capacity: 10 /20 /40 kg.
