graphite crucible
1. Description
Graphite crucible, which is divided into general type of graphite
crucible, special type of graphite crucible, high purity graphite
crucible.Graphite crucible, which is divided into general type of
graphite crucible, special type of graphite crucible, high purity
graphite crucible.
The main raw materials of Graphite crucible is natural crystalline
graphite. Therefore, it maintains the original natural graphite
various physical and chemical properties.
Our graphite crucible is made from selective raw material, and
added into anti oxidation composition .It has many advantages, High
purity machined graphite crucible, which is machined according to
customers' drawing from large graphite blocks.
