Magnesite

From Harbour Refractory — reference entry

Magnesite (MgCO3) is a source mineral for producing magnesia (MgO) used in basic refractories and other industries.

Description

After calcination, magnesite yields caustic or dead-burned magnesia grades with differing reactivity and density. Grading and chemistry are selected according to the intended refractory or chemical application.

Applications

Feedstock for MgO aggregates in basic refractories
Chemical and agricultural uses depending on grade
Magnesia-based mortars and castables

Packaging

Bagged or bulk on pallets with product and batch labels
Protect from moisture and contamination
Avoid excessive impact during handling and transport

Storage

Store in a dry, covered area away from moisture
Keep packaging sealed when not in use
FIFO for multiple lots to maintain uniformity
