Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Dolomite is a double carbonate of calcium and magnesium with the chemical formula CaMg (CO3)2 and is used as primary raw material for dolomite bricks. Fired dolomite bricks are far less sensitive to hydration than pitch-bonded dolomite bricks which have only been tempered. We also dip fired bricks in tar or vacuum-impregnated for some applications.

Fired Dolomite Bricks Properties. Dolomite refractory belongs to basic refractory material, which is resistant to erosion of basic slags and iron slags, with high refractoriness.And with high quality magnesite and dolomite as raw materials, and two-step calcining process, being made by high temperature sintering, dolomite bricks are excellent in high heat conditions such as high temperature ...

Dolomite bricks and cromodolomite concrete with high fire resistance should be used for electric shavings and steel rolling mills. This requires the dolomite to be good at refracting and to bear the slag in a sintered state, ie it is not decomposed into silicate and Mg alum, Ca, Fe and Mn alumina which are easily melted and corrosive.

Notes. Dolomite as a ceramic material is a uniform calcium magnesium carbonate. In ceramic glazes it is used as a source of magnesia and calcia. Other than talc, dolomite is the principle source of MgO in high temperature raw glazes. ''Dolomite matte'' stoneware glazes, for example, are highly prized for their pleasant ''silky'' surface texture. Dolomite by itself is refractory, but when combined ...

1,643 magnesia dolomite brick refractory products are offered for sale by suppliers on Alibaba , of which refractory accounts for 3%. A wide variety of magnesia dolomite brick refractory options are available to you, such as bending, moulding.

The fire retardant effects of natural mixtures of huntite and hydromagnesite have been investigated. ... Dolomite is a very white mineral that occurs naturally in the mixture and is removed during the grinding process. It finds industrial application due to its high

Fire retardant Dolomite XPS ABSTRACT This study describes the effects of ceria (CeO2) and dolomite [CaMg(CO3)2] additives on the pyrolysis behavior and fire resistive property of conventional intumescent flame retardant (IFR) coating system for I-beam steel substrate called ammonium polyphosphate-melamine-expandable graphite (APP-MEL-EG) system.

So, it was found that the flame retardant properties and storage stability of tripoli-containing suspensions increase, if a natural mineral decomposition was carried out in an alkaline solution. In the case of dolomite-containing suspen-sions, in contrast with tripoli-containing sistems, maximum fire-resistant, fire-extinguishing effi-

Dolomite matte glazes have traditionally been fired around cone 10 and have a pleasant-to-the-touch silky-feeling surface. It is not the dolomite that produces the matte effect, it is the MgO in the dolomite. But, the name has stuck because dolomite has been the most common source of MgO. Other materials can also source it (e.g. talc, a frit ...

 · Fire Clay Bricks. The Al2O3 content of the fire clay bricks is 30% ~ 40%. Fire clay bricks are kind of weak acid refractory brick products, which can resist the erosion of acid slag and acid gas. They have weaker resistance to alkaline substances. Clay fire bricks have good thermal properties and are resistant to rapid cooling and heat.

Fire Resistance of Steel Slag Aggregates Concrete, In this paper steel slag is considered as an aggregate which could improve fire resistance of concrete due to the fact that it is a material that occurs at high temperatures For this purpose, three concrete mixtures were prepared; concrete mixture with dolomite (reference mixture) and one concrete mixture with each of slags available in ...

Intumescent fire retardant (IFR) coating is designed to protect the substrate against fire. In case of fire, intumescent coating expends and form a thick porous char layer act as thermal barriers which is strong enough to protect the substrate from fire and retain its structural integrity.
