Keeping abreast of times, business markets demanded a finer grade carbon of more stable properties. Ahead of the rest of the industry, Toyo Tanso developed an "isotropic graphite" which is pressed by Cold Isostatic Press, having superfine isotropic microstructure. We have established world level technology that enables this isotropic graphite to fully exhibit its superior properties in the fields of nuclear power which requires high reliability, electrical discharge processing where accuracy is everything, and semiconductors which supports today's hi-tech wave.
