Sinter dolomite is also known as dead burned dolomite which is made by heating the raw dolomite at a temperature which is higher than 1650 deg C and preferably exceeding 1800 deg C. Sintering of raw dolomite is carried out with an aim to achieve a maximum bulk specific density and high resistance to hydration.
Half-burned dolomite. Half-burned dolomite (CaCOa MgO) is produced in relatively small quantities in Germany by the controlled calcination of dolomite at 800 to 900 °C. Little appears to have been published about the process. A small scale process was developed pre-1940 using a rotary kiln in which steam was injected into the flame to moderate ...

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 …
Calcined or sintered dolomite is a dolomite which has been subjected to a high-temperature heat treatment (about 1 500 °C for dead-burned (sintered) dolomite, and about 800 °C for caustic-burned dolomite which alters its chemical composition by driving off carbon dioxide).

Mashallah Rezakazemi, Zhien Zhang, in Comprehensive Energy Systems, 2018. 2.29.8.5 Calcium Oxide. Calcium oxide (CaO), generally recognized as burnt lime or quicklime, is a widely used material for desulfurization. The dry method of desulfurization with dolomite or lime involves in the solid–gas phase heterogeneous reaction that happens at high temperatures.
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.

Calcined or sintered dolomite is a dolomite which has been subjected to a high temperature heattreatment (about 1 500 °C for dead-burned (sintered) dolomite and about 800 °C for caustic burned dolomite which alters its chemical composition by driving off carbon dioxide.
Dolomite is a natural stone with double carbonate of calcium and magnesium having composition (CaCO3. MgCO3).It is formed in nature by action of magnesium-bearing solution (sea water, underground water or hydrothermal solution) on calcite — the process being called dolomitization. Dolomite is a widely occurring mineral, generally mined from ...
There is flexibility of reactivity from soft to hard burned, with possibility to produce dead burned dolomite. There is fuel flexibility since PRKs can use gas, liquid, or pulverized solid fossil fuels as well as waste fuels and biomass. Soft limestone feeds can be used, but they produce a lot of fines during calcination. ...

What is dead burned dolomite? Sintered Dolomite, also known as Dead-Burned Dolomite (DBD), is the product resulting from calcining the dolomite from 1,850ºC to 2,000ºC for a period of time, thus obtaining magnesium oxide crystals (periclase) and of calcium oxide. This product is an alternative to Magnesite.
Calcined or sintered dolomite is a dolomite which has been subjected to a high-temperature heat treatment (about 1 500 °C for dead-burned (sintered) dolomite, and about 800 °C for caustic-burned dolomite which alters its chemical composition by driving off carbon dioxide).
