Calcium Carbonate Granular Direct Compression Grade: Improving Flow, Compression & Tablet Performance

Insights
Calcium Carbonate Granular Direct Compression Grade is developed for efficient pharmaceutical and nutraceutical tablet manufacturing. Explore its applications, binder systems and formulation advantages.

Rubex International’s Calcium Carbonate Granular Direct Compression Grade (CCG DC Grade) is gaining increasing interest among pharmaceutical and nutraceutical manufacturers for its excellent flowability, superior compressibility and consistent quality. Developed for direct compression, it combines the benefits of calcium carbonate with physical characteristics suited for efficient tablet manufacturing.

What is Calcium Carbonate Granular?

Calcium Carbonate Granular is a specially processed form of calcium carbonate designed to provide better flow and compression characteristics than conventional fine powder. Through controlled granulation and suitable binder systems, calcium carbonate is converted into free-flowing granules that support consistent die filling and effective tablet formation.

Controlled particle size distribution and density further contribute to smooth processing and consistent tablet characteristics.

Applications

Calcium Carbonate Granular is widely used in pharmaceutical and nutraceutical formulations as a source of elemental calcium. It is suitable for calcium supplements, chewable tablets, mineral and multivitamin formulations, nutraceutical tablets and other high-calcium formulations. It is also used as an active ingredient in antacid formulations due to its acid-neutralizing properties.
