Dunite is a Magnesium Iron Silicate mineral produced from volcanic rocks. The name Dunite also known as Olivine Sand is given to members of the fosterite - fayalite solid-solution series.



It is a economical source of MgO, with good insulating properties, high resistance to alkaline oxides that make it excellent for use in bricks and unshaped refractory. Because of its high melting point and resistance to chemical reagents is an important refractory material and thus can be used in furnace linings and in kilns.


Primary Uses in Refractory Industry
Dunite is used as a raw material for 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. It has the advantage of excellent resistance against metals and slag penetration (due to high forsterite content), thermal shock, wear attack.

We offer Dunite for Refractory Application with various chemical compositions and numerous sizes as per clientâ??s requirement.
