Technologies in the area of green processes are constantly being developed and improved and many rely upon Graphite and Carbon products for success. The drive towards no fossil fuel electricity generation, for instance, had led to major advances in industries associated with Fuel Cells and Photovoltaics. Graphite and Carbon products are used somewhere in all these fields and Tokai Carbon has grades suitable for these applications.
The reliance on electrical equipment containing silicon chips is now overwhelming and most would not function without the addition of a silicon chip. However, without the use of high purity Graphite and Carbon products the manufacture of silicon itself would not be possible. The processes involved in the production of silicon, from extraction to purification and casting, use many different types of Graphite and Carbon parts as well as many post processes parts involving purification, coating and machining. Tokai Carbon has developed a range of products designed to be used in the Silicon Value Chain.
LED lighting is another rapidly emerging industry and Graphite is an integral part of the process of making the diodes that form the heart of an LED light.
