Material types of amorphous materials

There are many kinds of amorphous substances. Silica and its mixture with oxides of aluminum, sodium, magnesium, calcium and other elements constitute the oldest and most important inorganic glasses, and some mixtures of ⅵ a-ⅵ a and ⅵ a groups can easily obtain their glassy states (such as chalcogenide glasses). In addition to traditional glass and newly developed metallic glass, it also includes amorphous semiconductors, amorphous polymers, amorphous dielectrics, amorphous ionic conductors and so on. In recent 20 years, amorphous materials have developed rapidly and become an important new solid material because of their excellent physical and chemical properties and extensive technical applications.
