Product Description

 

Product Description

Graphite blocks are made from domestic petroleum coke, and contain more than 99% carbon. We have vibrational, moulded and isotropic graphite blocks. We can machine specific shapes based on the customer's requirements.

are widely used in machinery, electronics, semiconductors, polycrystalline silicon, monocrystalline silicon, metallurgy, chemical, textile, electric furnaces, space technology and biological and chemical industries. The graphite has the following characteristics:

1. Good electric conductivity and high thermal conductivity
2. Low thermal expansion and high resistance to thermal shock.
3. The strength increases at high temperature, and it can withstand over 3000 degrees.
4. Stable chemical property and hard to react
5. Self lubrication
6. Easy to process
