Dead burnt magnesite

dbmTengsheng Group is one of the few producer in the world capable of producing  Dead burnt magnesite with a purity more than 99%. In the market in which most suppliers do not get Dead burnt magnesite more than 98.5%. TSDBM is close to the perfect Dead burnt magnesite.


TSDBM has high purity(MgO>99%)and high density,with good lime/silica ratio.Since no low melting phases are formed, this results in very good resistance to high temperatures.Moreover has low boron and iron level to make the refractory materials more resistant to higher temperatures.TSDBM will replace most of the high purity Dead burnt magnesite.


*High purity,high density is the perfect raw materials of the refractory bricks unshaped refractory.
*The prodcut is available as run of kiln briquettes or separated into fractions,dependin on customer requirements.
