Silicon Carbide (SiC) Crucible Advantages

  • Extremely high-temperature resistance
    Capable of being used at temperatures up to 1600°C, they are ideally suited for high-temperature melting and chemical reaction processes.
  • Excellent mechanical strength and wear resistance
    With a flexural strength of 400 Mpa and a compressive strength of 2600 Mpa, it guarantees durability and stability under extreme conditions.
  • Excellent chemical stability
    The chemical inertness of silicon carbide makes it resistant to a wide range of chemicals, making it suitable for handling a wide range of chemicals and molten metals.
  • High thermal conductivity and thermal stability
    With a thermal conductivity of 100 W/mk and good thermal shock stability (400°C), it can maintain structural integrity during rapid heating and cooling.
  • Optimized design
    Uniform wall thickness and smooth surface finish ensure uniform heating at high temperatures and long-term reliability of the crucible.

Silicon Carbide (SiC) Crucible Applications

  • Laboratory research
    Silicon carbide crucibles can be used in research experiments, especially in the fields of materials science and chemical engineering, for melting and chemical analysis of high-temperature substances.
