Hydrothermal synthesis of dittmarite-group NH₄(Co_1-xMn_x)PO₄·H₂O particles as inorganic violet pigments.

ABSTRACT: Dittmarite-group NH₄(Co_1-xMn_x)PO₄·H₂O particles were prepared via a hydrothermal route. Single-phase platelike NH₄(Co_1-xMn_x)PO₄·H₂O particles were obtained from aqueous solutions containing MnCl₂·4H₂O, CoCl₂·6H₂O, and (NH₄)₂HPO₄, where the [Mn²⁺]/([Co²⁺] + [Mn²⁺]) mole ratios in the products were controlled by changing the MnCl₂ and CoCl₂ concentrations of the precursor solutions. The vivid violet colour of the ammonium cobalt phosphate (NH₄CoPO₄·H₂O) particles was maintained upon subs
