Nanoglass is a glassy material in which at least one of the dimensions is in the nanometer scale. Suitable techniques were used to produce glassy materials of different dimensions, for example, glassy spheres, 1D material, and 2D thin lms. Prof. Herbert Gleiter and his group initiated a work on nanometallic glasses [1-3]. They made bulk materials by compacting nanometallic glass spheres. In these materials, glass-glass interfaces were formed having reduced mass density relative to the core nanospheres [2,3]. Other nanomaterials reported so far are nanodimensional silicon oxide-based glasses as 1D materials or 2D thin lms. In this chapter, we will discuss about the present status of work carried out on nanometallic and nanodimensional silica-based glasses, respectively.
