magnesium oxide for electrical steel production

Our magnesium oxide steel produciton grade  are high purity, micronized grades of magnesium oxide that are used in the manufacture of silicon grain-oriented steel for high efficiency distribution transformer cores, specialty ceramics, and coatings. In the annealing process,they react with the silicon steel to form a glass-like film during the high temperature anneal, which then acts as an electrical insulator between core laminations in an electrical transformer.
