Description

Glauconite is a naturally occurring, hydrated potassium iron aluminosilicate mineral belonging to the mica group, recognized by the CAS registry number 102785-62-6. This green-colored mineral is valued for its unique ion-exchange properties, natural origin, and utility as a soil conditioner and adsorbent. It is a critical material for industries focused on sustainable agriculture, environmental remediation, and specialty chemical manufacturing.

Application

• Soil Amendment & Fertilizer Carrier: Used as a slow-release potassium source and soil conditioner to improve cation exchange capacity (CEC) and water retention in agricultural and horticultural applications.
• Water Treatment & Filtration Media: Employed as an adsorbent for the removal of heavy metals, ammonium ions, and other contaminants from industrial and wastewater streams.
• Drilling Fluid Additive: Functions as a viscosifier and shale stabilizer in water-based drilling muds for the oil and gas industry.
• Pigment & Filler: Serves as a natural green pigment and inert extender in paints, coatings, ceramics, and construction materials.
• Animal Feed Supplement: Incorporated as a source of essential minerals, including potassium and iron, in livestock and poultry feed formulations.
• Catalyst & Catalyst Support: Utilized in its natural or modified form as a catalyst or support material in various chemical synthesis processes due to its porous structure.

Quality Control

Our Glauconite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency for industrial applications. Quality is verified through parameters such as mineralogical composition, potassium oxide (K2O) content, particle size distribution, and cation exchange capacity. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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. Store away from strong acids and oxidizing agents.
