Burnt magnesite

Dead Burnt magnesite (DBM) is the main raw material for the production of basic refractory products and is widely used for the production of shaped and unshaped refractories. Our company offers burnt magnesites made in China. At present, China has the largest proven reserves of magnesite ores on the planet. Enriched magnesite ores are fed before firing in rotary kilns at temperatures from 1750 to 2100 ° C, and the final qualities of DBM have a high bulk density and size of periclase crystals. Fused magnesia (FM) is obtained by melting calcined magnesia in electric arc furnaces at temperatures above 3000 ° C. Fused magnesia is considered one of the best thermal and electrical insulators with high density, high purity, and large crystals.Dead Burnt magnesite (DBM) is the main raw material for the production of basic refractory products and is widely used for the production of shaped and unshaped refractories.

FM can be used in:

  • High-performance refractory bricks MgO-C for the metallurgical industry,
  • refractory refractory bricks for the cement and glass industry,
  • production of heating elements.
