Silicon carbide crucible is a high-temperature material mainly used for chemical reactions, heat treatment, and molten metal at high temperatures. The performance of silicon carbide crucibles may be affected in the following situations:
1. Temperature too high or too low: The operating temperature of silicon carbide crucibles is generally between 1400 ℃ and 1600 ℃. If the temperature is too high, it can cause the crucible to deform, crack, or burn through, thereby affecting its service life; If the temperature is too low, it may affect the heat treatment effect and reduce product quality.
2. Mismatch in chemical properties: Silicon carbide crucibles may be corroded in some chemical reactions, such as alkaline solutions, oxidizing gases, etc. These chemicals can cause deformation, cracks, burning through, etc., thereby affecting their service life.
3. Collision or vibration: If a silicon carbide crucible is subjected to collision or vibration during transportation or use, it may crack, damage, or deform, thereby affecting its service life and effectiveness.
4. Improper cleaning and maintenance: The cleaning and maintenance of silicon carbide crucibles require attention to methods and tools. Improper cleaning or use of inappropriate tools may scratch or damage the surface of the crucible, thereby affecting its service life and effectiveness.
5. Quality issues: The manufacturing and material selection of silicon carbide crucibles need to pay attention to quality issues. If the quality is not qualified, it may lead to issues such as uneven surface, large pores, and insufficient strength of the crucible, thereby affecting its service life and effectiveness.
In summary, silicon carbide crucibles require attention in terms of temperature, chemical properties, collision, maintenance, and quality to ensure their service life and effectiveness.
