Description

Chlorapatite CAS NO 1306-04-3 is a calcium phosphate mineral where chloride ions substitute for hydroxyl groups in the apatite crystal lattice. This compound is valued for its structural similarity to biological hard tissues, making it a critical material for advanced research and development. It is primarily sought by industries and institutions focused on biomaterials, geology, and environmental science for applications ranging from synthetic bone grafts to the study of mineral sequestration processes.

Application

• Biomedical & Dental Materials: Serves as a precursor or dopant in the synthesis of bioactive ceramics and coatings for orthopedic and dental implants to enhance osseointegration.
• Geological & Environmental Research: Used as a model mineral in studies of igneous and metamorphic rock formation, ore deposit geology, and the environmental fate of chloride and phosphate ions.
• Fertilizer & Soil Science: Investigated as a slow-release phosphate fertilizer component and for studying nutrient cycling and ion exchange in agricultural systems.
• Catalyst & Sorbent Development: Explored as a support material or active component in catalysts and for the sequestration of heavy metals from aqueous solutions.
• Analytical Reference Standard: Supplied as a high-purity standard for X-ray diffraction (XRD), spectroscopy, and other analytical techniques in laboratory settings.
• Advanced Ceramics & Composites: Incorporated into specialty ceramics and composites to modify thermal, electrical, or mechanical properties for industrial applications.
