Dolomite Powder is the limestone powder with the composition of CaCO3 and MgCO3 pertaining to 100% in combination, the proportion being varied as per the mining zone. Because of Dolomite Powder useful properties, it is additionally being employed as Fillers by paints, steel, detergents and ceramics. We are offering an extremely adaptable vary of mineral powder which is occupied in numerous industries. Dolomite mineral may be a double Calcium Carbonate and metal and it exhibits a powdered structure.

Its use improves properties like whether or notability, reduces shrinkage, fissure development, and water absorption. We use the best quality machines to ensure the quality of our Micronized Dolomite Powder. We have lapidarian a distinct segment jointly of the leading Dolomite Ore makers in the Republic of India (Southern Asia). In nature, extended variations within the composition of dolomite about lime and pericline percentages area unit found.

When the percentage of CaCO3 increases by 10% or more over the theoretical composition, the dolomite mineral is termed 'calcitic dolomite', 'high-calcium dolomite' or 'lime-dolomite'. With the decrease in the percentage of MgCO3, it is called 'dolomitic limestone'. With the variations of MgCO3 between five to 100 percent, it's referred to as 'magnesian limestone', and up to five MgCO3 or less it's taken to be the sedimentary rock for all purposes in trade and commercial parlance. Micronized Dolomite mineral typically contains impurities, chiefly silica, alumina, and iron oxide. For industrial functions, the percentage of combined impurities should not go beyond 7% above which, it becomes unsuitable for industrial use. It is then used just for road ballasts, building stones, flooring chips etc.

Properties

1. Tactile properties: It is slightly rough and abrasive.
2. Visual properties:

• Color: It is often in pink or pinkish and can be colorless, white, yellow, gray or even brown or black when iron is present in the crystal white, grey, pink color.
• Luster: It is vitreous to pearly to dull.
• Streak: It is white.
• Diaphaneity: It is opaque.

3.Structural properties:

• Hardness: 3.5-4 mosh.
• Specific gravity: 2.84-2.86.

4. Affinity to water: It has the ability to adsorb and absorb moisture. However, its solubility in pure water is poor                    though it readily disperses in water.

5.Affinity to oil: It has low oil absorption capacity.

• Thermal conductivity: 5.1 W m-1 K-1 at 20 °C, it exhibits a two-stage decomposition (750 ° Dolomite and MgO; 900 ° CaO and MgO).
• Specific heat capacity: 900 J kg-1 K-1 at 20 °C.
• Mean thermal expansion coefficient: 4.1×10-6/°C.
• Melting Point: 2570 °C.

7. Electric properties: It is poor conductor of electricity.

8. Combustion properties: It is non explosive and non-inflammable.

9. Chemical properties: It’s effervescing is weak with warm acid or when first powdered, with cold HCl.
