Title
Transparent ceramics: Transmission physics and consequences for materials selection, manufacturing, and applications
Other Title
Transparente Keramik. Transmissionsphysik sowie Konsequenzen für die Werkstoffauswahl, Herstellung und Anwendungen.
Abstract
The fundamental difference of translucent and transparent transmission gives rise to conditions for correct photographic presentation and transmission measurements. Comparing amorphous, single crystalline and sintered polycrystalline transparent materials, prerequisites of clear transparency are derived for inherent materials properties and for optimum microstructures. Manufacturing principles differ for transparent cubic and non-cubic ceramics and have to respond (i) to microstructural requirements, (ii) to available raw materials, and (iii) to shape, size, and properties of products. Present and potential future applications are addressed and are governed by a sensible balance of individual needs in different fields of the industry and of costs of development and manufacture.
