Setting Changes of Amalgam Surfaces Observed by a Scanning Electron Microscopic Motion Picture

Abstract

The changes of the phases on a setting amalgam surface were observed by a scanning electron microscope and recorded on a videotape. The image reproduced on a TV monitor was converted into a 16-mm motion picture with a low speed movie camera. The movie showed the dynamic process of the change of matrixes and residual alloy particles developing new γ₁ and γ₂ crystals and voids.
