Glass is an example of crystalline structure
WebAmorphous structure means that atoms are not organized according to a well-ordered, repeating arrangement as in crystals. Glass-ceramics are made of small grains surrounded by a glassy phase, and have properties in between those of glass and ceramics. The table below provides a summary of the main properties of ceramics and glass. WebCrystalline quartz contains a highly ordered arrangement of silicon and oxygen atoms, but in quartz glass the atoms are arranged almost randomly. When molten SiO 2 is cooled rapidly (4 K/min), it forms quartz glass, whereas the large, perfect quartz crystals sold in … Example \(\PageIndex{1}\): Water.
