Calcined (Burnt) Limonite

The final product is supplied in fine powder form with consistent particle size and reliable chemical characteristics suitable for demanding industrial applications. In the paint and coating industry, calcined limonite powder is widely used as a functional filler and natural iron-oxide pigment. Its red-brown to dark brown color tone, excellent heat resistance, and weather stability make it suitable for industrial paints, primers, anticorrosive coatings, and decorative finishes. The powder disperses well in both solvent-based and water-based systems, contributing to color uniformity, opacity, and long-term durability while helping formulators optimize production costs.

Calcined limonite powder is also extensively applied in construction materials, including cement, concrete products, tiles, bricks, and mortars, where it provides stable coloration, bulk density control, and improved thermal performance. In rubber and plastics compounds, it functions as an inert mineral filler that enhances dimensional stability, hardness, and abrasion resistance.
