product_detail
High purity graphite powder refers to graphite powder with carbon content above 99.9%, featuring ultra-low ash and impurity content. Strict impurity control is critical for energy storage, semiconductor and photovoltaic auxiliary materials. Trace metal impurities will cause leakage, efficiency decay or contamination of precision components.
Ultra-fine high-purity graphite powder is commonly used as conductive agent for lithium battery anode, conductive paste, thermal conductive composite and CVD process auxiliary materials. It has uniform particle distribution, good dispersion and low outgassing rate under vacuum. Compared with ordinary graphite powder, it has stable electrochemical performance and fewer particle defects.
Jiecheng Graphite provides test reports of fixed carbon, ash content and particle size distribution for every batch of high purity graphite powder. We separate production lines for industrial grade and electronic grade to avoid cross-contamination. It is suitable for battery factories, conductive paint manufacturers and semiconductor thermal field supporting customers.
