Differences between raw, calcined and sintered dolomite or
Sintered dolomite, also known as dead-burned dolomite, is produced by high-temperature calcination of raw dolomite, between 1,400 and 1,800 degrees, in a vertical furnace. During this process, the dolomite completely breaks down and turns into pure calcium magnesium oxide. Sintered dolomite is a high-quality material with a wide range of ...

Calcined Dolomite
Notes. Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which provides an buffering because MgO …
