Double beam optical dilatometry

Abstract

Thanks to the new double optical dilatometer, the ceramic scientist has the possibility to follow the behaviour of the sample during the heat treatment without interfering with the process. The applications brake the limits of traditional dilatometry in many fields of research: • Incoherent materials, like the expansion and contraction of the raw glaze applied on the surface of a ceramic ware, or the behaviour of an incoherent granular flit • Softened materials, like the behaviour of a glass above the transition temperature, where the surface tension starts to pull the edges and to make the sample shorter • Sintering kinetics: studying the relationship between time and temperature during a sintering process • Extremely thin samples, like tape cast substrates can be analysed with regard to thermal expansion and sintering behaviour.
