Description

Glauconite CAS NO 102785-63-7 is a naturally occurring, potassium-rich phyllosilicate mineral of the mica group, recognized for its distinctive green color and ion-exchange properties. This mineral is valued for its ability to slowly release essential nutrients like potassium and iron, making it a key component in sustainable agricultural and horticultural amendments. It serves critical functions in industries ranging from water filtration and soil conditioning to animal feed supplements and geological research.

Application

• Slow-Release Fertilizer & Soil Conditioner: Used as a natural source of potassium, iron, and magnesium to improve soil structure and provide long-term nutrient availability for crops.
• Water Filtration Media: Employed in filtration systems for its cation-exchange capacity to remove heavy metals and soften water.
• Animal Feed Additive: Incorporated as a mineral supplement in livestock and poultry feed to provide essential trace elements.
• Drilling Fluid Additive: Utilized in the oil and gas industry as a viscosifier and shale stabilizer in water-based muds.
• Pigment & Colorant: Processed for use as a natural green pigment in ceramics, paints, and cosmetics.
• Geological Research & Standard: Serves as a reference material in sedimentology and stratigraphy studies due to its authigenic origin.
• Horticulture & Lawn Care: Applied in potting mixes and turf management to enhance moisture retention and nutrient delivery.
• Remediation Agent: Used in environmental projects for the sequestration of contaminants in soil and groundwater.

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 including mineralogical purity, potassium oxide (K2O) content, particle size distribution, and cation exchange capacity (CEC). 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 prevent moisture absorption and contamination from foreign materials. Separate from strong acids and oxidizing agents.
