    Abstract: The novel carriers consist of steel cores which have an iron oxide- containing coating of the formula (FeO)x . Fe2O3 where x = 0.1 - 1. The carriers are stable and effective over long cycle times (6 .10 prints). … The carriers are obtained by treating steel cores (steel spheres) with defined small amounts of sulphuric acid of defined concentration, partial oxidation of the treated cores and drying at 60-150 DEG C at
