Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability.

But the following points should be noted:

1. To avoid damage to the graphite crucible caused by impact or falling from a height. Be careful when using, handle with care, and take a look at the surrounding environment.

2. The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame.

3. Prevent strong corrosive flames from directly spraying the sides and bottom of the crucible.

4. Before use, it is necessary to heat bake and dry
