Summary

Silica was examined under the electron microscope —directly by transmission and indirectly in the form of carbon replicas — and the change in structure resulting from alkaline treatment was examined. It was found that the original silica has a larnellar structure with marked surface relief. After treatment with alkali and washing with water, its surface becomes covered with round particles about 100–200 A in size, a phenomenon which results from the hydrolysis of, alkali silicate and separation of colloidal silicon dioxide.
