Noncrystalline state and the glass transition

It was mentioned earlier (Section 3.4) that all materials can be rendered amorphous. What is often not recognized by chemists is that a large variety of materials - catalysts, catalyst supports, xerographic photoreceptors, optical fibres, large-area solar cells and many biominerals - are noncrystalline (Elliott et al, 1986). Noncrystalline solids possess no long-range order and their structure is akin to that of a frozen liquid. Most 

An ideal glass has been defined as one in which T approaches T . Nonideality of a glass
