High Purity Graphite Crucible

Advantages of high purity graphite crucible

High purity graphite crucible is generally in the shape of cups, bowls or cylinders and it has very significant advantages.

Extremely strong high-temperature resistance

It can be stably used in an ultra-high-temperature environment ranging from 1500℃ to 3000℃ without deformation or melting.

Highly stable chemical properties

It has strong resistance to most corrosive chemical substances such as acids and alkalis.

Great thermal conductivity

Its heat conduction is uniform and rapid, which can effectively improve the heating efficiency.

High mechanical strength

It has good thermal shock resistance and can withstand rapid temperature changes without easy cracking.

Good lubricity

It can reduce the adhesion of materials to the crucible wall and facilitate the pouring of materials.

Long service life

You can reuse it many times, thus effectively reducing the cost of use.

In addition, you can also choose isostatic pressed high-purity graphite crucibles, molded high-purity graphite crucibles, vacuum-impregnated high-purity graphite crucibles or other types of high-purity graphite crucible products according to different usage requirements.
