Minor components such as TiO₂ and P₂O₅ are important in natural and commercial glasses, including optical fibers and glass wool insulating materials. The structural behavior of P⁵⁺ in silicate glasses and melts is fairly well known, whereas that of Ti⁴⁺ remains more controversial, perhaps because the oxygen coordination environment surrounding Ti⁴⁺ may be a composition‐dependent variable.
