Product Overview

Marble powder is a crystalline form of calcium carbonate (CaCO₃). Due to its metamorphic origin, it possesses a unique interlocking crystal structure that gives it slightly higher hardness and distinct weathering properties compared to sedimentary calcite. At Rajgarh Minerals, we source premium white marble lumps from the famous marble belts of Rajasthan. These are crushed and pulverized in our advanced milling units to produce a brilliantly white, highly durable powder. Marble powder is extensively used in the construction industry for premium wall putty, textured paints, and architectural coatings where weather resistance is critical. In the plastics industry, it serves as a highly effective filler for PVC pipes and rigid profiles, providing excellent dimension stability and impact strength. It is also widely used in the manufacturing of artificial marble and solid surfaces.

Frequently Asked Questions

What is the difference between marble powder and calcite?

Both are CaCO₃, but marble is crystalline (metamorphic) while calcite is typically sedimentary. Marble offers slightly better weather resistance for exterior coatings.
