Some Aspects of Vitrification, Amorphisation and Disordering and the Generated Extent of Nano-Crystallinity

摘要: Historically, glass is often viewed as a remarkable translucent substance though usually made from the simplest raw materials upon effect of firing. Nature, itself, best instance to learn how different temperature changes can provide various glassy states, altering very slow rates occurring within geological time scales (e.g. obsidians – volcanic rocks consisting natural acidic silicate glasses) extremely fast, result fast energetically driven collapse (e.g., by impact meteorites, yielding melted droplets then cooled tektites). Mimicking evolution, however, man became responsible for creation further families wide variety and amorphous (geopolymers), which have gradually appeared through human creativity, particularly during last 100 years. Properly chosen procedure rapid extraction heat (often called quenching) turned up be efficient route successful glass-formation (vitrification, repeatable process) almost all substances (thus allowing preparation glasses sorts inorganic materials, including metals) in contrast traditional chemical approach, seeking just an appropriate composition vitrify under customary self-cooling [1,2].
