摘要：
A method for the preparation of chromium-doped (pink), manganese-doped (brown) and cobalt-doped (blue) alumina pigments consisting of spherical particles of broad size distribution (<5 µm) is reported. The procedure, based on the room-temperature hydrolysis of aerosols generated from a mixture of aluminum sec-butoxide and a solution of the corresponding metal nitrates in sec-butanol, yields amorphous solids. The temperature of calcination and the composition of the so produced powders were varied to investigate their effects on the color properties of the pigments, which were also characterized in terms of their composition, crystalline structure and electrokinetic behavior.
