This product stands out for its ultra-high purity of 99.9% min, with extremely strict limits on heavy metals and microbial contaminants, ensuring full compliance with global pharmaceutical safety standards. Its 5-10μm particle size provides excellent compressibility, making it ideal for direct compression tablet production, reducing the need for additional binders and improving the uniformity of tablet formulations. With a neutral to slightly alkaline pH value, it effectively neutralizes excess stomach acid as an antacid, and its high calcium content makes it an effective nutritional supplement for dietary products. It solves the pain points of low-quality pharmaceutical excipients, such as high microbial counts, inconsistent particle size, and poor compressibility.
The pharmaceutical-grade calcium carbonate has an average particle size of 5-10μm, with a minimum purity of 99.9%. The moisture content is controlled at ≤0.15%, and the pH value of a 10% aqueous suspension ranges from 7.5 to 8.5. Lead and arsenic contents are limited to ≤5ppm and ≤1ppm respectively, meeting the most stringent pharmaceutical safety standards. The loss on ignition is between 43.0% and 44.0%, and it complies with USP <1111> microbial testing standards and EP 7.0 quality specifications. It has excellent compressibility, making it suitable for direct compression tablet production, and it is packaged in food-grade HDPE drums, with each drum containing 25 Kilograms of product. Each batch undergoes third-party testing to ensure compliance with pharmaceutical regulations.
This product is primarily used as an active ingredient in calcium supplement tablets and capsules, providing a high concentration of elemental calcium for the treatment and prevention of calcium deficiency. It is also used as an antacid ingredient in over-the-counter medications, neutralizing excess stomach acid to relieve symptoms of heartburn and indigestion. In pharmaceutical tablet production, it serves as a filler and binder, improving the hardness, disintegration time, and uniformity of the tablets. Additionally, it is used in pediatric dietary supplements, providing a safe and effective source of calcium for children.
