Isotropic Graphite

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 microstrucutre. 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.

Characteristics of Isotropic graphite 

Highly purified graphite products are used also for the manufacturing material of the single crystal / polycrystalline silicon ingot or thin si film for solar cells.

There are a wide range of applications, most notably the use of high purified graphite in optical fiber manufacturing equipment. It is also used in electrical discharge machining, continuous casting, hot press, and as vacuum evaporation crucible.
