Glass-ceramics contain one or more crystalline phases dispersed in a residual glass phase. The proper selection of bulk composition of the glass to allow for crystallization of desired phases is crucial. These crystalline phases are, in turn, chosen for one or more specific attributes. Such attributes include greater chemical durability than the precursor glass; superior mechanical toughness; high resistance to radiation damage; sites and structures within a crystalline framework with advantageous properties for “active” functions (e.g., luminescence and ionic diffusion); and a lack of a center-of-symmetry, thereby allowing properties forbidden to glass and many crystals (e.g., piezoelectricity and the electro-optic effect). These innovative applications of glass-ceramics owe their importance and continuing interest to hard-to-combine properties.

The talks in this webinar expanded on the topics presented in the March issue of MRS Bulletin.
