Fluorine-bearing phosphates

Definition

Fluorine-bearing phosphates are a class of minerals that contain both phosphate ions (PO₄³⁻) and fluoride ions (F⁻) within their structure. These minerals typically exhibit unique properties and classifications due to the presence of fluorine, which can affect their chemical behavior, stability, and occurrence in nature. Their understanding is crucial in the study of phosphate mineral chemistry as they illustrate how the incorporation of different anions can lead to a diverse range of mineral forms and characteristics.
