Analysis and pilot production of graphite and other minerals and materials
Explore our laboratory and pilot plant offerings.



We have a well-equipped laboratory where we can carry out all necessary and common analyses relating to graphite and other minerals and materials

Loss on ignition (LOI), fixed carbon, total graphitic carbon (TGC)

Bulk and tapped density

Thermogravimetric analysis (TGA)

Particle size distribution by sieving or laser particle analyser

Specific surface area (BET)

Spectroscopy with WD-XRF
…and a variety of other specific analyses.


Manufacturing of customised products
Technical centre / Pilot Plant
We have a comprehensive technical centre that enables us to carry out the following process steps, among others:

Flotation

Production of expandable graphite

Micronisation using jet and impact mills (Hosokawa Alpine AFG 100)

Spheronisation to produce spherical graphite "SPG"

Air classification (ATP 50)

Chemical purification (alkaline or acid-based)


Solutions for a wide range of applications
Services in the laboratory & technical centre

Independent analyses according to graphite industry standards

Comprehensive characterisation and evaluation of graphite samples (ore, semi-finished and finished products)

Competent interpretation of analysis results, also from other laboratories

Cooperation with leading laboratories for specific analyses such as GDMS or Raman analyses

Special mineralogical analyses (MLA, QEMSCAN, XRD etc.)

(Co-)development of special samples for industrial or research applications

Performance of test work such as flotation, purification, sieving, micronisation

Production of expandable graphite incl. comprehensive characterisation

Production of coated purified spherical graphite from flotation to carbonized pitch coated battery anode material (cSPG), including physical, chemical and electrochemical characterisation (battery tests)

Recycling of anode material, including production scrap and scrap materials

Suitability testing of graphite for specific applications and for typical industry process steps: flotation, purification, micronisation, conversion to expandable graphite, suitability as battery graphite, etc.

Supervision, execution and monitoring of tests in external laboratories in Germany and abroad (incl. China)

Co-operation with relevant laboratories, e.g. in Canada, Australia and China

Sample preparation service: We convert your material into samples according to your customers' requirements with corresponding analysis values and certificates

"Graphite problem solving": We help you to find specific solutions to address challenges with your material
In addition to small laboratory quantities, larger quantities of graphite and other materials can be produced in the technical centre through sieving, mixing, micronizing in a jet mill or impact mill and using an air classifier.
