Glass

Alumina is added to glass formulations to improve mechanical strength, hardness, thermal and optical properties. These properties are important in end-use applications such as TFT glass, cover glass, and fiberglass for industrial, marine, armor and aerospace industries.  Alumina is also a high quality alternative to natural minerals in many glass formulations.  Due to it’s substantially lower impurity content, specifically iron oxide, alumina provides greater UV transparency and less coloration.
