Usage of graphite crucibles

Graphite crucibles have a broad range of usages, which can be roughly summarized into the below fields:

1. Chemical field

In chemical experiments, graphite crucibles are usually used to heat reactants for chemical reactions. Due to it has good high temperature resistance and thermal conductivity, it will not be damaged or deformed in high-temperature chemical reactions.

2. In some cases, certain substances need to be heated to extremely high temperatures for chemical reactions. At this time, graphite crucibles are needed for experiments. For instance, when preparing oxygen, potassium hydrogen dioxide needs to be heated to more than 1000 degrees Celsius to obtain oxygen. At this time, graphite crucibles are needed for heating.

3. In some special chemical reactions, strong acids or strong bases are needed to catalyze the reaction. These strong acids or strong bases will corrode

Ordinary glass containers, therefore, ordinary test tubes or beakers cannot be used. Graphite crucibles can withstand strong acids or strong bases and will not corrode, so they can be used for such type of reactions.
