Siliziumkarbid

SiC

Silicon Carbide (SiC) is a covalently bonded ceramic compound that, in metallurgical grades, doubles as a combined deoxidizer, recarburizer, and silicon source for steel and cast iron. When charged to a melt, SiC dissociates so that its Si and C reduce dissolved oxygen and slag oxides (FeO, MnO), generating exothermic heat that stabilizes bath temperature and protects yield of Mn and other alloys. In EAF and induction practice it lowers FeSi and carbon consumption while improving slag foaming. Foundries use it for nucleation support in grey and ductile iron, sharpening graphite structure and machinability. Typical addition is roughly 0.3-1.5 wt% of charge, tuned to oxygen load and target chemistry. This grade runs SiC ≥ 90%, F.C ≤ 2.0%, and Fe₂O₃ ≤ 1.5%, supplied as 0-10 mm or 10-50 mm to match EAF charging versus ladle/inoculation needs. It also serves refractory and abrasive lines. Every lot ships with COA (EN 10204 3.1) and MTC, drawn from multi-regional sourcing with Gebze bonded stock (24-48h) and CIF Marmara delivery, 20 MT FCL. Send your grade and sizing for an RFQ.
