OPTIMIZATION OF SOLID-STATE SYNTHESIS PROCESS OF ADVANCED CERAMIC MATERIALS: INFLUENCE OF MIXING CONDITIONS

In this paper, the effect of mixing process on solid state reaction of solid oxide material mixture was studied. Lead piezoelectric ceramic specimens 0.5 Pb(Zn^sub 1/3^,Sb^sub 2/3^)O3-0.5 Pb^sub 0.98^La^sub 0.02^(Zr^sub 0.48^,Ti^sub 0.52^)O^sub 3^ prepared by different mixing procedures, were conducted under different conditions such as order, combination and mixing time. The phase formation, composition nature, structural properties of powder mixture was analyzed by X-ray diffraction. The obtained results for different mixing processes make the solid state reaction method more selective, taking into consideration the attraction forces between the reactants and the electronegativity of oxide reactants.
