Polyamorphism
From Wikipedia, the free encyclopedia
In materials science polyamorphism is the ability of a substance to exist in several different amorphous modifications. It is analogous to the polymorphism of crystalline materials. Even though amorphous materials exhibit no long-range atomic structure, the different phases can vary in other properties, such as the density.
Examples of polyamorphism are the existence of six-coordinated and four-coordinated amorphous silicon, and the different density phases of amorphous ice.
