透過型電子顕微鏡によるケイ酸三カルシウム表面の微構造観察

抄録

The surface microstructure of tricalcium silicate (C₃S) was observed by transmission electron microscopy (TEM). The tricalcium silicate specimen was dispersed in ethanol or isopropanol. It was then placed on a copper mesh with a collodion film that had an amorphous layer on the surface of each grain. The amorphous layer was caused by the hydration reaction of C₃S with water in the dispersants. The irradiation by an electron beam caused the layer to change into CaO crystallites with a concurrent formation of silica-rich domains.
