Description

Glauconite CAS NO 102785-61-5 is a naturally occurring, complex potassium iron aluminosilicate mineral belonging to the mica group. This greenish mineral is valued for its unique ion-exchange, adsorption, and slow-release nutrient properties, making it a versatile functional material. It serves as a critical raw material for industries seeking natural, sustainable solutions for soil conditioning, water purification, and as a carrier for agricultural amendments.

Application

• Soil Amendment & Fertilizer Carrier: Used as a natural soil conditioner to improve cation exchange capacity (CEC), water retention, and as a slow-release carrier for potassium and micronutrients.
• Water Treatment & Filtration Media: Employed as an adsorbent medium for the removal of heavy metals (e.g., lead, cadmium) and ammonium ions from industrial and wastewater streams.
• Animal Feed Additive: Incorporated as a natural mineral supplement to provide essential trace elements and potentially act as a mycotoxin binder in livestock and poultry feed.
• Drilling Fluid Additive: Functions as a viscosifier and shale stabilizer in water-based drilling muds for the oil and gas industry.
• Pigment & Filler: Utilized as a natural green pigment in paints, coatings, and ceramics, and as an inert filler in various construction materials.
• Horticulture & Substrate Component: An essential component in professional growing media, potting mixes, and green roof substrates for its structural and nutrient-holding properties.
• Catalyst & Catalyst Support: Investigated and used as a natural, low-cost catalyst or support material in certain chemical synthesis and environmental catalysis processes.

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 a series of tests including mineralogical identification, chemical composition analysis, and physical property determination. A Certificate of Analysis (COA) detailing key parameters such as potassium oxide (K2O) content, iron content, cation exchange capacity (CEC), and particle size distribution is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep the container sealed when not in use to prevent moisture absorption and contamination. Separate from strong acids and oxidizing agents.
