What is Dolomite Powder?
Dolomite powder is a common rock-forming mineral with a composition of calcium magnesium carbonate. Its chemical formula is denoted as CaMg(CO3)2.
Its whiteness and purity are two important factors that make it a raw material for the paint industry. Further, its hardness and density makes dolomite powder a vital ingredient in the construction industry.
Dolomite is the second most abundantly found carbonate mineral. It exists as the primary component of sedimentary and metamorphic rock. It is also commonly found in hydrothermal deposits.
Dolomite is the primary ore for magnesium metal and is quarried for building material, road stone, or refractory brick production.

Properties of Dolomite Powder
Here is a detailed description of the physical, chemical, and electrical properties of dolomite powder supplied by the renowned paint industry mineral supplier.
- Dolomite powder has a rough and abrasive texture.
- It may appear pinkish, white, yellow, grey, colorless or even black/brown.
- According to the dolomite manufacturer its luster may vary from vitreous to pearly to dull.
- Also, this raw material for the paint industry and glass industry is opaque.
- Its value on the hardness scale lies between 3.5 to 4 Mohs.
- Further, it has both adsorption and absorption tendency towards moisture.
- Dolomite powder disperses in the water but remains insoluble.
- Its oil absorption capacity is low.
- It is non-explosive and non-inflammable on combustion.
- Lastly, it is a poor conductor of electricity.
