When naturally occurring magnesium carbonate(magnesite) is fired at around 800-1500 it becomes what is known as ''caustic calcined magnesite''. The resulting magnesium oxide grains have the outer form of the magnesium carbonate and depending on the firing temperature are porous and more or less reactive due to their large inner surface area. It's also called industrial grade caustic calcined magnesite
Application: In the production of magnesium salt, MgO oxide is used as raw material to react with acid. In Refractory, Mgo is used as the Refractory of crucibles. In energy plants, MgO is used to remove sulfur trioxide that are harmful to plants and the environment. In the rubber and plastic industry, Mgo is used as Filler, acid acceptor, anti-coking component and curing acid.
Packing: 50kg pp bag with PE coating outside/ PE inner bag, 1250kg Jumbo bag.
Dead Burned Magnesite is made of high quality magnesite, which is flotation and concentration, briquetting, calcination, high temperature sintering method and fired in vertical kiln, with high MgO content, low Apparent Porosity and high Bulk Densitey. It is an excellent raw material for making bricks and molding whole refractory products.
