STRENGTHENING GLASS WITH ALUMINA
Alumina in Glass Manufacturing:
Purity, Strength, and Optical Excellence
Glass is an extremely versatile material with a range of key properties that make it unique and widely used in industries like construction, manufacturing, optics, electronics and telecommunications, among others.
Strengthening Glass with Alumina
Alumina improves glass properties by increasing mechanical strength, hardness, thermal stability, and optical clarity. These benefits are important for applications like TFT glass, LCD glass, cover screens, armor, and industrial fiberglass used in marine, aerospace, and defense industries.
As a better alternative to natural minerals in glass formulations, alumina offers high purity with fewer impurities, particularly in iron oxide content. This results in clearer glass with greater UV transparency and less coloration.
Our calcined alumina has low impurity levels, ensuring consistent batch chemistry and maintaining melt viscosity and flow behavior. This consistency helps produce uniform and high-quality glass.
Alumina provides the reliability and consistency needed for advanced glass performance, opening new possibilities for innovation and application across various industries. It helps glass products achieve both strong structural qualities and excellent optical performance in many applications.
