The sintered dolomite powder is used for patching the fettlings of openhearth and electric steel furnaces, and the dolomite products (including slugs) are used for lining steel smelting converters and in part electric furnaces. Dolomite refractory materials are characterized by high resistance .
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 rocks are useful building materials (as structural and ornamental stone, and for special cements) and refractories (materials that can withstand high temperatures) as fire-resistant stones, particularly for furnace linings.

The decrease in the weight loss indicates the increase in fire properties for the particleboard. Thus, the fire resistance of the particleboard was improved by the coating process. It was determined that calcite, used in the surface coating, and also with a contribution from the content of dolomite, has a positive effect on the fire resistance.
Chert vs Dolomite Characteristics. Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Chert vs Dolomite characteristics assist us to distinguish and recognize rocks.

Dolomite is used for many purposes in ornamental stone, concrete aggregate, and magnesium oxide for magnesium production or as a fire retardant for plastic composites. In addition to its use in glue production, melamine is also used as a fire retardant in the production of paper, plastics, and paints.

Dolomite produces a very weak reaction to cold, dilute hydrochloric acid; however, if the acid is warm or if the dolomite is powdered, a much stronger acid reaction will be observed. (Powdered dolomite can easily be produced by scratching it on a streak plate.) Dolomite is very similar to the mineral calcite.
At higher temperatures (above about 800 degrees F), high-heat-resistant concrete is generally needed. Light-weight aggregates have proven to be more heat resistant and so that is the first step--use lightweight. When temperatures get extremely high, (above 1000 degrees F), calcium aluminate cement produces a fire-resistant concrete.

What characteristics influence fire resistance? Fire resistance of concrete is influenced by aggregate type, moisture content, density, permeability and thickness. Limestone, dolomite and limerock are called "carbonate" aggregates because they consist of calcium or .

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.
