Thermal Shock Resistant Oval Crucible , Industrial Silicon Carbide Crucible

Crucibles play a vital role in numerous industrial and laboratory settings where materials are subjected to high-temperature heating. These sturdy vessels are made from materials with superior refractory characteristics, ensuring they can withstand and operate effectively in the harshest thermal environments.

Silicon carbide graphite crucibles are designed for outstanding performance in high-temperature scenarios, such as the smelting of metals. Composed of a blend of silicon and carbon, these crucibles possess distinctive attributes that render them well-suited for melting metals 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 Thermal Conductivity: Made with natural graphite materials and silicon carbide, produced by isostatic pressing, the crucible walls are thin, and heat conduction is fast.
• Significant Energy Saving: High thermal conductivity material crucibles save a lot of energy during user operation.
• Chemical Stability: Resistant to most molten metals and metal oxides.
• Thermal Shock Resistance: Can handle rapid heating and cooling cycles without cracking.

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 requiring precise thermal control
• Die-casting of zinc alloy and aluminum alloy
