Abstract
A composition used for coating machine parts used in the production of pig iron or steel may include aluminum nitride (AlN) in a proportion of from 10% by weight to 40% by weight, one or more metal-oxidic substances in a proportion of from ≧2 to 10% by weight, of which at least one comes from the group consisting of aluminum oxide, zirconium oxide, and LD converter dust, and an inorganic binder in a proportion of up to 70% by weight, where the % by weight are based on the total weight of the composition. A suspension based on the composition, and the use of the composition or the composition suspension for coating machine parts used in the production of pig iron or steel, are also disclosed.
