Formula BT® (Energy Materials)


It's not only a product, it’s a philosophy

The name Formula BT® encompasses carbon and graphitic powders developed and manufactured by Superior Graphite primarily for use in the electrical energy marketplace. Formula BT® takes advantage of the unique continuous thermopurification treatment patented by Superior Graphite. This electro-thermal process exposes the raw materials, such as natural flake or vein graphite, synthetic graphite and various coke products to temperatures up to 2800ºC so that the volatiles, gases and impurities are vaporized.

A variety of milling and classification processes coupled with mechanical and chemical treatments complete the competencies of Superior Graphite. This ...
