Sourcing Magnesium Oxide (Caustic Calcined / Dead Burned)? ChemicalDekho connects you with primary producers like Tamilnadu Magnesite (TANMAG). Access high-purity Magnesia for refractories, animal feed, and environmental applications.
Magnesium Oxide (CAS 1309-48-4) is processed from natural magnesite. 'Caustic Calcined' grades are highly reactive and used in animal feed supplements, fertilizers, and wastewater treatment (pH control). 'Dead Burned' grades are used to manufacture refractory bricks for steel furnaces. Listings include Light and Heavy density powders tailored to specific reactivity needs.
Secure consistent supply with verified MgO content and Loss on Ignition (LOI) specs, supported by detailed chemical and physical analysis reports.

May cause metal fume fever if inhaled as fresh fume (from welding/burning). Dust acts as a mild laxative if ingested. Irritating to eyes.
Chemically they are both MgO. 'Light' has a very low bulk density and is fluffy, used in pharma/rubber. 'Heavy' is dense and granular, used in refractories.
Magnesium Oxide reacts with water to form Magnesium Hydroxide (Mg(OH)2), also known as Milk of Magnesia. It must be kept dry.
Yes, Feed Grade MgO is a standard supplement for cattle to prevent 'Grass Tetany' (Magnesium deficiency) and acts as a rumen buffer.
It is MgO that has been fired at very high temperatures (>1500°C), making it unreactive and extremely heat resistant, perfect for lining steel furnaces.
