The carbon-based refractories typically contain MgO, Al2O3, or dolomite bonded by pitch or resin with up to 30-wt-pct natural flake graphite. In addition to the natural flake graphite, refractory oxide, and pitch, metallic additions are often made to enhance brick high-temperature properties.
ideally dolomite used for refractory bricks manufacture should have about 45.6 mole% of mgco 3 and 54.4 mole% f 15 of caco3 and it should be hard, compact with uniform texture containing very little of iron, silica and alumina as they reduce the refractoriness of dolomite bricks. 2.2 high purity dolomite for the production of doloma …
After calcining, dolomite can be made into various dolomite refractory materials.

The Dolomite sinter or Dead-burned dolomite is generally used in the refractory industry for the refractory made by firing dolomite, with or without additives, at high temperature to produce dense, well-shrunk particles. This refractory is widely used wherever steel is refined using basic slag and can stand temperatures up to 2.300ºC.

Sintered dolomite may serve as the refractory basic material for the production of basic refractory bricks.
Dead burnt (D.B.) dolomite is sthe term generally used for the refractory made by firing dolomite, with or without additives, at high temperature to produce dense, well-shrunk particles. In basic converters the bricks employed are generally of D.B. dolomite and sometimes also of D.B. magnesite.
Dolomite was traditionally used as fettling material for the hearth of furnaces. Dolomites are, as magnesite, used as refractories bricks after being subjected to calcination and sintering at 1600–1700 °C. Dolomite bricks are used in basic soil converters (electric furnaces).

Dead burnt refractory dolomite is produced in rotary kilns. Generally high-grade dolomite, containing combined impurities less than 3%, is selected for dead burning. As it is difficult to densify high purity dolomite in a rotary kiln, it is customary to use some mineralizers to facilitate dead burning. Iron oxide is a common additive.

Dolomite brick is the most important stable refractory under the working conditions of Argon Oxygen De-carbonization (AOD). For AOD applications, the Dolomite bricks should have positive Permanent Linear Change (PLC) on re-heating. A positive PLC dolomite brick has higher life and most suitable for joint less refractory lining with no cobble stoning defect.
