The tendency of glass forming substances to supercooling is discussed in connection with the existence of large or irregular groups in the melts of such substances.

If the size of these groups makes their direct addition to the crystal lattice difficult, and if the forces within them are so strong as to prevent a rapid disintegration of the groups, the melt will tend to supercooling and glass Cited by: Introduction to Electrochemical Science and Engineering is an ideal textbook for undergraduate engineering and science students and those readers in need of introductory-level content.

Furthermore, experienced readers will find this book useful for solidifying their electrochemical background. Provided are compositions having high conductivity and high work-function.
