Magnesium Oxide Powder
Magnesium oxide is formed commercially by heating magnesite to 600-800 °C, which drives off most of the CO2. It has good thermal conductivity and electrical resistivity at elevated temperatures
Magnesite Grain- dead-burned magnesia in granular form in size suitable for refractory purposes
Seawater Magnesite- Dead-burned magnesia made by a chemical process using seawater or other solutions (brines)
