  • Glasses, and the liquids from which they are generally quenched, conspicuously lack translational periodicity and from this experimental fact it is a short step to assume that glasses are essentially disordered. In silicate glasses, the strongly covalently bonded silicon and oxygen atoms are thought to form a network structure within which ionically bonded 'network-modifying' atoms such as Li, Na, Ca, Mg and Fe substitute randomly in suitable interstices. Taken to extremes, this view leads to a… CONTINUE READING
