Last week, the Engineering Department received a few RFQs requesting natural graphite. Graphel has received questions on the topic of natural graphite and synthetic graphite. This article explores the characteristics, production processes, and applications of natural and synthetic graphite and clarifies any confusion about the two materials.

 

1. Composition:

– Synthetic Graphite: Produced from a carbonaceous feedstock through high-temperature processing, synthetic graphite exhibits a highly ordered atomic structure. It boasts a purity level exceeding 99% carbon, with the remaining impurities mainly comprising ash and volatile materials.

– Natural Graphite: Derived from naturally occurring mineral deposits, natural graphite is formed through the metamorphism of organic material. It consists of varying carbon content, typically ranging from 15% to 95%, with the remaining composition comprising impurities such as ash, sulfur, and trace elements.
