Coating composition, and method for manufacturing high silicon electrical steel sheet using thereof

摘要

There are provided a coating composition for siliconizing, and a method for manufacturing a high silicon electrical steel sheet using the same. The coating composition includes: a Fe-Si-based composite compound sintered powder having a grain size of -325 mesh and containing 20-70% silicon by weight; and a colloidal silica solution containing 15-30 part by weight of silica solid matter with respect to 100 part by weight of the sintered powder.
