Detailed Product Description

Magnesia's formular MgO, comprised calcined Magnesite,Dead burned Magnesite,Medium Magnesite ,High-purity Magnesite and Electro-fused Magnesite.

1.the feature of Caustic Calcined Magnesite:

caustic calcined magnesite,another name light burned magnesite is made from narure magnesium ore processed in reverberatory kiln,rotary kiln and calcined in boiling furnace.the products were calcined uniform,possess stable quality,high purity and well activeness. The products are used widely in paper making,chemical industry,pharmaceuticals,animal husbandry,desulfurizing,rubber making,refractories and building industry etc.

the spcification of  caustic calcined magnesite

MgO:80-90%

SiO2:3-6%

CaO:2-4%

IG.loss:6-9.0%

Size: 120-325 mesh passing through  95% min

2.the feature of Dead burned Magnesite:

Dead burned magnesite is selected  from natural magnesite ore,it is produced by mine-selecting,purifying,calcining in shaft kiln.it is an ideal material for unshaped refractory material,the final products are used in open hearth furnace, bottom of the electric and furnace's lining tamping.

3.The feature of the electro-fused Magnesite

 The material of eletro-fused magnesite sinter is selected from special grade A natural magnesite ore or high-purity caustic calcined magnesite,which is fused in are furnace to finish the products.the products are high purity,big crxstalline grain and compact texture,good heat-vibration stability  and refuses resistance. it is used for making high quality magnesia bricks,magnesia-carbon bricks and  unshaped refractory material.
