Gelling preparation of starting materials for dry and wet syntheses of silicate minerals

Creators Ikeda Ko

Gelling technique on the preparation of starting materials of silicates for both dry and wet (hydrothermal) syntheses has been fundamentally reinvestigated on the following components, SiO_2, Al_2O_3, Fe_2O_3, Cr_20_3, MgO, FeO, NiO and CaO by precipitating with excess ammonia water in ethyl alcohol solutions. On the basis of solubilities at each pH for each component, a general procedure for the preparation of starting materials including Na_2O and K_2O has been proposed.
