Monolith/bulk glasses

Glass-ceramics of the P203-Al203-Ca0-type are produced as monolithic bulk glass-ceramics and as composites of glass-ceramics and metals. Both types are used as biomaterials for bone substitution in human medicine. 

Composite glasses prepared via the sol-gel technique are of high optical quality and large monolithic bulk forms can be made for various photonic functions [22,23,79,88,101-103] such as lasing, optical power limitation, nonlinear optical response, and so on. Figure 10.9 presents an example of a solid dye laser based on multiphasic composite monolith doped with BASF LFO-240 laser dye placed in optical resonator. 

These highly porous glasses retain a rigid and exposed interfacial surface area (typically 300-1000 m g ), whereas conventional organic polymer beads swell and shrink in different solvents, often with unpredictable effects on catalysis Functionalization of a monolithic (largest dimension 1 mm) gel affords a bulk catalyst sample. This obviates the need for filtration to recover the catalyst tweezers can be used instead ...

The development of novel optical devices requires suitable materials which have the required chemical and photochemical stability, with appropriate optical features, which can also be made into usable forms such as thin films and bulk pieces. Since the sol-gel process9,10,218 219 offers a very attractive possibility with the ability to incorporate organic materials in inorganic matrices at low temperatures in the form of monolithic glasses or thin films, it has opened the way to many possible applications in optics1,60,190,192,193,196,220-222 and electrooptics2,223,224.
