    • closedAccess   Ceramic pigments with sphene structure obtained by both spray- and freeze-drying techniques 

      Lyubenova, Teodora; Matteucci, Francesco; Costa, Anna Luisa; Dondi, Michele; Carda Castelló, Juan Bautista Elsevier (2009)
      The present study is focused on the procedure of spray- and freeze-drying techniques for the preparation of Cr-doped sphene pigments (CaSn0.98Cr0.02 SiO5, CaTi0.98Cr0.02SiO5) from an aqueous solution of precursor salts, ...

    • closedAccess   Malayaite ceramic pigments: A combined optical spectroscopy and neutron/X-ray diffraction study 

      Cruciani, Giuseppe; Dondi, Michele; Ardit, Matteo; Lyubenova, Teodora; Carda Castelló, Juan Bautista; Matteucci, Francesco; Costa, Anna Luisa Elsevier (2009)
      Ceramic pigments based on the Cr-doped malayaite structure were synthesized by solid state reaction and characterized by optical spectroscopy and combined X-ray and neutron powder diffraction in order to elucidate the still ...

    • closedAccess   Synthesis of Cr-doped CaTiSiO5 ceramic pigments by spray drying 

      Lyubenova, Teodora; Matteucci, Francesco; Costa, Anna Luisa; Dondi, Michele; Ocaña Jurado, Manuel; Carda Castelló, Juan Bautista Elsevier (2009)
      Cr-doped CaTiSiO5 was synthesized by spray drying and conventional ceramic method in order to assess its potential as ceramic pigment. The evolution of the phase composition with thermal treatment was investigated by X-ray ...
