Electrical Steel

Messi’s MgO are high purity, micronized electrical steel 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, MgO 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.
