Concepts of Glass-Ceramics,liquid becomes thermodynamically unstable with respect to one or more crystalline phases. Whether or not crystals will form as a result of this instability is dependent on the rate of cooling and the kinetics of crystallization of the particular crystalline species that are involved.

Rather, only selected sources which are useful within the context of the discussion will be referenced; special attention will be given recent findings. Nonetheless, at the o

In addition, for practical purposes, it is necessary to define the smallest usable volume. This varies from fractions of a gram (in reflective beads) to many kilograms (for massive o

A typical qualitative curve of n, index of refraction, versus λ, wavelength, is given in Figure 1 for a large portion of the electromagnetic spectrum for a material

The paths by which it propagates tell a complex story of static and dynamic stress configurations, weaknesses of design and material inhomogeneities. In short, it leaves a record of the event and it leaves it in a form which can be read. It is

Chemical corrosion is much more deleterious to the life of the refractories since it involves the dissolution of some or all of their components. A

Second, a synthesis of the understanding of composition and structure effects will be presented; and third, important problems in this area will be discussed. The theoretical review will first consider a general theory of conductivity, followed by more specific discu
