The maximum temperature of graphite crucible can reach 1800 degrees Celsius and it can be used for a long time!

It mainly depends on the operating conditions. If used in the air at over 600 degrees Celsius, it will start to oxidize, and the service life will not be very long.

Graphite crucibles can withstand high temperatures of 1660 degrees Celsius and can be used continuously at this temperature. Graphite crucibles have such excellent performance because the ore used is mainly a flake like crystalline type, and the chemical properties of crystalline graphite are very stable. Due to the stable chemical properties of graphite itself, it can withstand acid, alkali, and organic chemical solvents, which lays a certain foundation for the properties of crucibles.

What should I pay attention to when using it?

1. To avoid unnecessary damage, first, handle with care during transportation to prevent damage from falling, shaking, and falling;

2. It should be stored in a dry and ventilated place or placed on a wooden frame to avoid affecting the performance of the crucible due to the humid environment;

3. Before use, it is necessary to gradually raise the temperature of the crucible to 500 ℃ through baking or other methods;

4. When adding materials, they should be added according to the capacity of the crucible. Avoid adding too much material, otherwise it may cause the crucible to expand and affect subsequent use.

5. When using, do not add excessive combustion aids, otherwise it may reduce the lifespan of the crucible; Additionally, rotating the crucible once a week can also extend its service life appropriately.

6. According to the shape of the crucible, select the appropriate furnace tool and crucible clamp. When clamping, the middle of the crucible should be clamped to avoid local hand force causing damage to the crucible.
