Cordierite, with the chemical formula Mg2[Al4O3(SiO3)5] and CAS number 1302-88-1, is a silicate mineral belonging to the cyclosilicate group. It is characterized by its unique crystal structure, which consists of a framework of silicate tetrahedra linked by aluminum and magnesium ions. Cordierite typically exhibits a vitreous to pearly luster and can display a range of colors, including blue, gray, and brown, often with a pleochroic effect, meaning its color can change when viewed from different angles. It has a relatively low hardness on the Mohs scale, typically around 7, and is known for its thermal stability and resistance to thermal shock, making it valuable in ceramics and refractory materials. Additionally, cordierite has a low thermal expansion coefficient, which contributes to its utility in high-temperature applications. Its occurrence is often associated with metamorphic rocks, particularly in regions of high-grade metamorphism, and it can also be found in some igneous rocks.
