To meet the increasing quality requirements in the market and to be able to supply best and constant products to our customers, we have implemented a detailed monitoring of the single process steps in our production.

The quality parameters for the end products can be agreed with each customer to meet his specifications.

The customer receives its product with a certificate of analysis.

The retain samples are stored for a defined time in our special customer's warehouse.

Continuous quality controls enable the traceability from the production of slurry via wafer production up to the recycled PEG and SiC.
