Effect of the nature of the iron salt on the hydrothermal modification of ferrosilica gel

The effect of iron(III) salts (chloride or nitrate) on the hydrothermal modification of the texture and phase composition of ferrosilica gel has been studied. Special features in the crystallization of prepared specimens as a function of the nature of the anion of the initial iron salt have been revealed by x-ray phase analysis and nuclear gamma-resonance spectroscopy.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 24, No. 2, pp. 251–253, March–April 1988.
