Physical and chemical characteristics of biogenous silica

Estimation of the silica balance in the ocean requires clarification of the trend of dissolution of biogenous silica. We used biogenous silica in our experiments to compare silica gel and opal. From the results, convenient methods can be devised to estimate the easily soluble parts of biogenous silica. The soluble parts of diatomaceous silica vary considerably with the different species and
