Global Silicon Steel Grade Magnesium Oxide Market Strategic Research Report

Scope of the Report

The global Silicon Steel Grade Magnesium Oxide market size is predicted to grow from US$ 129 million in 2025 to US$ 161 million in 2032; it is expected to grow at a CAGR of 3.2% from 2026 to 2032.

Grain oriented electrical steels (GOES) are iron-silicon alloys that were developed to provide the low core loss and high permeability required for efficient and economical electrical transformers. GOES is the most energy efficient electrical steel and used in transformers where energy conservation is critical. High-purity active magnesium oxide is used to form insulating “glass” layer of oriented grain on silicon steel (transformer steel) surface and give special electromagnetic properties to steel. This is achieved by coating steel surface with aqueous slurry of magnesium oxide which reacts with silicon on steel surface during high-temperature annealing until transparent layer of magnesium silicate. Magnesium oxide shall have a high degree of purity and contain very low level of elements such as chlorine, bromine, calcium, fluorine and sodium which can form an unacceptably high electrical conductivity of insulating layer. Magnesium oxide shall also have a very small particle size to obtain slurry which is stable and has desired characteristics of coating.

Global key players of silicon steel grade magnesium oxide include Shanxi Yinsheng Technology, Tateho Chemical, ICL-IP, etc. The top three players hold a share about 48%. China is the largest producer, has a share about 64%, followed by Europe and Japan, with share 17% and 9%, respectively. The largest market is Asia-Pacific, with a share about 69%, followed by Europe and North America, with share 21% and 7%, separately.
