Properties:

  1. Excellent high temperature resistance: Clay graphite crucible relies on the excellent thermal conductivity of graphite and can withstand high temperatures up to 1800°C without softening or melting. It is especially suitable for high temperature experiments and industrial smelting.
  2. High strength: Graphite and clay are combined to form a high-strength composite material, which makes the crucible less likely to break when subjected to external impact and has good durability.
  3. Strong corrosion resistance: The natural corrosion resistance of graphite enables clay graphite crucible to be used for a long time in various corrosive environments, and is suitable for storing and processing various corrosive solutions.Features of use
    Clay graphite crucible has a wide range of uses and excellent performance, specifically:

    1. Wide applicability: Whether in laboratory analysis, alchemy, or other chemical experiments, clay graphite crucible is suitable for various high-temperature operations and is an ideal choice.
    2. Long service life: Due to its superior material, clay graphite crucibles can generally be used hundreds of times, greatly reducing the frequency and cost of replacement.
    3. Simple and convenient maintenance: The crucible surface is smooth and easy to clean, and daily maintenance is extremely simple, providing users with great convenience.

    Precautions
    In order to ensure the best performance and long service life of the clay graphite crucible, the following points should be paid attention to during use:

    1. Avoid oxidizing environments: It is not recommended to use crucibles with elements, substances or solutions that are easily oxidized to prevent oxidative damage.
    2. Appropriate selection of capacity: When using, you should select an appropriate crucible capacity and control the generation of heat to avoid damage to the crucible due to a sudden rise in temperature.
    3. Avoid long-term high-temperature use: In corrosive solutions such as strong acid and strong alkali, long-term high-temperature use should be avoided as much as possible to avoid affecting the durability of the crucible.

    In conclusion
    In summary, clay graphite crucible has become an indispensable tool for high-temperature operations in laboratories and industrial environments due to its excellent high temperature resistance, high strength, and corrosion resistance. Correct use and maintenance can ensure its long service life and stable performance. Clay graphite crucible shows wide application prospects in smelting, chemical industry, laboratory and other fields, and is an ideal choice for your high-temperature experiments and production.
