Description

Apatite CAS NO 64476-38-6 is a naturally occurring calcium phosphate mineral group that serves as a critical source of phosphorus. Its primary commercial value lies in its role as the principal raw material for the production of phosphoric acid and phosphate fertilizers, which are essential for global agriculture. This mineral is also vital for industries including metallurgy, where it is used as a flux, and in the manufacturing of specialty chemicals, animal feed supplements, and certain ceramic materials.

Application

• Fertilizer Production: The primary application is as a phosphate rock feedstock for manufacturing phosphoric acid, superphosphates, and other agricultural fertilizers.
• Chemical Manufacturing: Serves as a key raw material for producing various phosphorus-based chemicals, including industrial phosphates and flame retardants.
• Metallurgical Flux: Used in steel and metal production to remove impurities and control slag viscosity during smelting processes.
• Animal Feed Supplement: Processed into dicalcium phosphate or other forms to provide essential dietary phosphorus and calcium for livestock and poultry.
• Ceramics & Glass: Acts as a source of phosphorus pentoxide (P₂O₅) in the production of certain optical glasses, enamels, and ceramic frits.
• Environmental Remediation: Utilized in water treatment and soil remediation for its ability to immobilize heavy metals like lead and cadmium.

Quality Control

Our apatite products are sourced and processed to meet stringent industry specifications for phosphate content and impurity levels. Quality is assured through rigorous in-process and batch testing, including analysis of P₂O₅ (BPL) content, major impurities (e.g., silica, iron, aluminum oxides), and trace elements. A Certificate of Analysis (COA) detailing the chemical and physical specifications is provided with each shipment to ensure compliance with your process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C). Keep away from incompatible materials such as strong acids. As a mineral product, it is generally stable but should be protected from excessive moisture to prevent caking.
