Description

Aragonite is a naturally occurring crystalline polymorph of calcium carbonate (CaCO₃), distinct from the more common calcite. This mineral form is valued for its unique physical properties, including higher density and specific crystal morphology, which make it suitable for specialized industrial applications. It serves as a critical functional filler and additive in sectors such as polymers, paints & coatings, agriculture, and construction, where its particle shape and reactivity offer performance advantages.

Application

• Polymer & Plastic Composites: Acts as a functional filler to improve mechanical strength, dimensional stability, and surface finish.
• Paints, Coatings, and Sealants: Used as an extender pigment to enhance durability, weather resistance, and whiteness.
• Agricultural Amendments: Provides a slow-release source of calcium and carbonate to adjust soil pH and improve nutrient availability.
• Construction Materials: Incorporated into cement, mortars, and tiles to modify setting time and enhance final product properties.
• Animal Feed & Nutrition: Serves as a calcium supplement in livestock and poultry feed formulations.
• Water Treatment: Utilized in filtration media and for pH correction in various water treatment processes.
• Cosmetics & Personal Care: Functions as a gentle abrasive and bulking agent in products like toothpaste and exfoliants.

Quality Control

Our Aragonite is produced and tested under a rigorous quality management system to ensure batch-to-batch consistency and compliance with relevant industrial specifications. Key parameters such as purity, crystal phase identification, particle size distribution, and heavy metal content are routinely monitored. A Certificate of Analysis (COA) documenting these results is available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed to minimize exposure to atmospheric moisture and carbon dioxide.
