Lepidolite

Description

Lepidolite belongs to the mica group and represents a solid-solution series chemically defined as the polylithionite-trilithionite series, characterized by the formula K(Li,Al)3(Al,Si)4O10(F,OH)2. Often misidentified as a lithium feldspar, it is fundamentally a phyllosilicate mineral. It serves as a significant geological source of lithium and acts as a primary extraction point for rubidium, which occupies potassium sites within the crystal lattice. In ceramic applications, lepidolite is valued as a raw material for the introduction of lithium oxide into glaze formulations and bodies, and it serves as a precursor in the industrial synthesis of lithium carbonate.
