Oxidation And Chemical Resistance Metal Melting Silicon Carbide Graphite Oval Type Crucible

Crucibles are indispensable in various industrial and laboratory applications where substances need to be heated to high temperatures. These robust containers are crafted from materials that exhibit exceptional refractory properties, ensuring they remain stable and functional even in the most extreme thermal conditions.

Silicon carbide graphite crucibles are engineered to provide exceptional performance in high-temperature applications, such as metal smelting processes. These crucibles are crafted from a compound of silicon and carbon, which gives them their unique properties and makes them ideal for fusing materials like aluminum, copper, and brass.

One of the key features of silicon carbide crucibles is their chemical stability. They can resist most molten metals and metal oxides up to their maximum operating level, ensuring that the dissolved substance remains uncontaminated and the crucible undamaged. Furthermore, silicon carbide has one of the lowest thermal expansion coefficients, allowing the crucible to handle rapid heating and cooling cycles without cracking.

Oval type crucible suitable for automated operations with robotic arms. A partition is added in the middle of the crucible, enabling simultaneous melting and working.

• High-Temperature Resistance: They can endure high temperatures, making them suitable for a wide range of metallurgical and foundry processes.
• Uniform Heat Distribution: The oval shape of these crucibles facilitates better heat circulation, ensuring uniform temperature throughout the melt.
• Controlled Pouring: The design of the oval crucible, including the pouring spout, allows for a controlled pouring process, which is essential for precision casting.
• Chemical Stability: SiC graphite crucibles exhibit chemical inertness, preventing reactions with the materials being processed and preserving their purity.
• Thermal Shock Resistance: These crucibles are capable of withstanding rapid temperature changes without the risk of damage.

Oval crucibles are designed to offer a larger surface area for containing samples, which can be beneficial for applications that require more space or for experiments involving powder mixing or grinding. The shape of an oval crucible can also facilitate easier pouring and transferring of molten materials compared to round crucibles, as they often have straighter sides instead of a rounded bottom.

Oval type crucibles are used in various industrial and laboratory settings, including:

• Melting of metals
• Synthesis of advanced materials
• High-temperature processes that require precise control over thermal conditions
