Fayalite
ID: fayalite
Fe2SiO4
Description
Fayalite functions as the iron-dominant end-member within the olivine solid-solution mineral group. Characterized by an orthorhombic crystal system, this silicate mineral possesses defined unit cell dimensions of a = 4.82 Å, b = 10.48 Å, and c = 6.09 Å. In ceramic and geological contexts, fayalite is primarily recognized for its iron silicate composition, which influences its thermal behavior and chemical interactions during high-temperature processing and glaze formation.
