The materials need many weeks, sometimes even months to become high quality products.

Carbon products are the result of a complex process. Once extruded, the green bodies spend several months in different types of furnaces. In a special scheme, individually adjusted to every product, the duration and the temperatures of up to 3.000 °C are determined – it is thus guaranteed that the graphite body will fulfil the high requirements when it is in operation. Graphite Cova products withstand highest mechanical chemical and thermal loads.
