Strengthening additive for runner clays NITRO- FESIL ® AL is a composition of silicon nitride, iron silicides (FexSiy) and antioxidant. There also may be small amounts of free iron.
Strengthening additive for runner clays NITRO-FESIL® AL is meant for used in running clays to improve corrosion stability, persistence to heat stocks and abrasing effects of slag and iron.
NITRO-FESIL® AL is produced on a special facility by high-temperature synthesis under high pressure of nitrogen (up to 20 MPa).
