The difference between high purity and medium coarse graphite crucible
Nov 24, 2023
Graphite crucible is a very common laboratory supplies, mainly used for high temperature experiments and melting experiments. The graphite crucible is divided into high purity and medium coarse two, their difference is mainly in the material and use.
High purity graphite crucible is made of high purity graphite, has excellent high temperature resistance and chemical stability, suitable for high temperature experiment and melting experiment and other need to keep pure occasions. High purity graphite crucible will not burn, blister, crack or deformation at high temperature, so it is widely used in high temperature experiments and can withstand temperatures as high as 3000℃.
The material of the coarse graphite crucible is worse than that of the high-purity graphite crucible, but it is cheap, and it can replace the high-purity graphite crucible in some experiments with low temperatures or not very high requirements. The graphite content of medium and coarse graphite crucible is low, but because of its cost-effective advantage, it is still used in the experiment.
In general, high purity graphite crucible and medium coarse graphite crucible have their own advantages and applications. No matter what kind of graphite crucible, we should cherish the use and pay attention to maintenance. Only by maintaining the performance and quality of laboratory supplies can we better complete the experimental task.
