Product Description
Components used in semiconductor environment have high requirements for particle size. It not only needs to apply the good physical properties of graphite, such as high temperature resistance, corrosion resistance and plasma resistance, but also has high requirements for the purity and machining accuracy of graphite.
We use imported purification equipment of international well-known brands, which can extract the purity of graphite processed parts to 5-50PPM, and the ash content of specially ordered products can be less than 2PPM.
The main applications include graphite thermal field in semi-con single crystal furnace, including heating element, crucible, insulation cylinder, packaging fixture, etc.
