Grecian Magnesite offers a big variety of deadburned magnesia grades for the production of refractories with diverse chemical purities (ranging from 85% up to 97%) and bulk densities. All products are characterized by their forsteritic composition, SiO2/CaO ratio which is greater than 2 and their very high hydration resistance, making them especially suitable for refractory applications.
Iron & Steel / refractories
Steelmaking is the largest market sector for the refractory industry. Magnesia based refractories (basic refractories) have the ability to withstand high temperatures, show high resistance to basic slags and sufficient strength to withstand mechanical abuse and abrasion in hot environments. Also where steel cleanliness is of the highest importance, basic refractories are recommended. Basic refractories are divided into shaped and unshaped types.
