Grounded Calcium Carbonate (GCC)

Pure Mineral. Reliable Quality. Built for Performance.

We manufacture high-purity Grounded Calcium Carbonate (GCC) using advanced grinding and classification processes to ensure consistent particle size, superior whiteness, and high brightness. Our GCC is derived from naturally occurring, high-quality limestone and is carefully processed to maintain its physical and chemical integrity.

With controlled fineness and excellent dispersion characteristics, our GCC enhances the performance of end products in plastics, paints, rubber, paper, adhesives, sealants, and various industrial applications. It provides improved dimensional stability, gloss, opacity, and surface finish—making it an essential ingredient in many formulations.

Produced under strict quality assurance protocols, our Grounded Calcium Carbonate is available in multiple grades and particle sizes to suit diverse industry requirements. At Hari Udhyog, we are committed to delivering consistent quality, cost-effective solutions, and sustainable mineral products that contribute to better product performance and long-term value.

Key Features

Chemical Composition of Grounded Calcium Carbonate (GCC):

Our Grounded Calcium Carbonate (GCC) is composed primarily of high-purity calcium carbonate (CaCO₃), typically ranging from 96% to 99%, sourced from naturally occurring, premium-grade limestone. It contains minimal impurities, with trace amounts of magnesium oxide (MgO), silica (SiO₂), iron oxide (Fe₂O₃), and alumina (Al₂O₃), all well within industry-accepted limits.

Typical Chemical Composition:

Calcium Carbonate (CaCO₃): 96% – 99%

Magnesium Oxide (MgO): ≤ 1.0%

Silica (SiO₂): ≤ 0.5%

Iron Oxide (Fe₂O₃): ≤ 0.1%
