Electro-Thermal Treatment / Purification Technology

Superior Graphite’s unique technology for high-temperature treatment/purification of carbonaceous materials is based on a resistant-heated fluidized bed. This Electro-Thermal continuous process is used to consistently treat and/or purify granulate calcined petroleum coke, natural flake graphite and other carbonaceous materials at temperatures approaching 3000°C.

Through fluidization in an inert gas stream, precursor materials are purified, and simultaneously the other properties such as crystallinity, lubricity and resiliency are improved as the materials pass through the high temperature bed.
