Olivine is a ecnomical source of MgO for its low cost sourcing, with good insulating properties
, high melthing point that make it excellent for use in bricks and unshaped refractory and resistance to chemical
reagents is an important refractory material like basic refractories along with Dead Burnt Magnesite in
manufacturing of Magnesia Bricks and Monolithic Refractories such as Ramming Mixes, Gunning Mixes, Tundish Spray
Mixes and Fluxes high resistance to alkaline oxides.
