Electro fused magnesia

High purity Electro fused magnesia uses the best raw material and is finished thourgh the process of flotation separation,purification,comminuting,briquetting,being calcined in the super-high temperature oil-fired shaft kiln.


TSFM is high purity and high quality Electro fused magnesia .TSFM is not only high MgO content and properly controlled sulfur,iron,boron and other impurity content. Our Electro fused magnesia have a wider range of application.


TSEMAG used to produce high grade magnesia bricks and also used to produce refractory material. Our Electro fused magnesia contains the lowest impurity,more suitable for application for High magnesium oxide ceramics,Electrical insulating materials,raw mater for insulators ,etc.
