FM98 Large crystal fused magnesia,Mgo≥98%,You can determine the amount of other things. 100MESH\200MSH\0-1\1-3\3-5.
(dry ramming mix centrifugal process casting mix sulphate)
Technics: Large crystal fused magnesia uses high purity caustic calcined magnesia as raw material which is fused by electric arc furnace to finish. It has the features such as high purity, dense crystal, good resistance to slag erosion, good thermal shock stability etc.
Fused magnesite sand are manufactured by high purity caustic calcined magnesite through electro-fusing,a part of SiO2,moves to the surface because of the huge difference in the specific which well grown crystals,well crystal perfection and structure homogeneity,excellent chemical stability,good corrosion resistance to slag and high stength at high temperature.it is main raw .material for manufacturing magnesia or magnesia-carbon Bric refractories.The manufactures are mainly used in regenerative chamber in the large scale glass furnace by floating method,electrical furnace,convert furnace,house hold electrical appliances as electrical insulating materials and so on.
