high purity graphite rod(customized production)

Short Description:

The raw material of high purity graphite rod has large carbon content and small particle size than ordinary graphite rod, and the particle size is generally 20 nanometers to 100 nanometers. It is characterized by high strength, high density, high purity, fine particle size, high chemical stability, dense and uniform structure, high temperature conductivity, more wear-resistant than ordinary graphite rod, self-lubrication, easy processing and so on.
