Research

Expertise in graphite is both guiding philosophy and our commitment. This know-how ranges from the raw material supply and state-of-the-art production methods right through to stringent quality control.

We are constantly optimising manufacturing processes and developing new graphite products for new applications. We also work closely with research institutes and universities with a view to expanding our knowledge, taking part in forward-looking projects.

New and advanced methods of analysis also make it possible for us to boost our capabilities for offering a range of different product specifications.

Precisely defining the specification of a product requires much more than simply controlling the carbon content and grain size. 

As a result, we conduct analyses of bulk density, density, deformability, compressibility as well as electrical resistance, depending on the required specification of each product. The specific graphite surface area is determined using the BET method, while fine particle size distribution - less than 40 microns - is analysed using the laser diffraction method.

Ash analysis is carried out with emission spectroscopy (ICP), X-ray fluorescence analysis (RFA) or by means of atomic absorption spectroscopy (AAS).

The COND grade range was developed for specialised applications requiring graphite with high electrical conductivity. In addition, we have also developed new types of expandable graphite, primarily for use in fire-retardant applications.
