Abstract
Two cobalt layer silicates were synthesized by hydrothermal treatment at 275℃ and 54 atm from corresponding stoichiometric coprecipitate of cobalt hydroxide and silica. From IR adsorption spectra and X-ray diffraction patterns, one sample was proved to be cobalt montmorillonite[Co3(Si2O5)2(OH)2], while the structure of the other was cobalt antigorite[Co3Si2
O5(OH)4] of one silica layer combined with an octahedral layer of the type Co32+(OH)6.
