Product Description
Graphite Product Supplier
Graphite block is made of domestic petroleum coke, with carbon content above 99%. We have vibrated,molded and isotropic graphite block. They are widely used in such fields as mechanical , electronics, chemical industry and other new industries.
We can machine to specific shapes according to customers' requirements.
Nature:
1. Thermal stability: According to the quench acute thermal using conditions of graphite blocks, we will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of graphite plate.
3. Impact resistance: Graphite plate can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite plate
