چکیده
|
Molybdates zn1-xcoxmoo4 (0≤ x ≤0.3) were elaborated by the sol-gel method with ph=3.the results obtained by drx show a single-phase domain starting from 500°c for x ≤ 0.3 isostructural to znmoo4.the powder of zn0.7co0.3moo4 treated at 500°c and 700°c is formed by nano-sized primary crystallites of size between 80 and 160 nm. the colorimetric parameters (l a* b*) of powders obtained at 700°c present a degree of high bluing.
