摘要
Slurries stability and powder dispersion are highly dependent on both the pH and their density. The analysis of these parameters allows us to keep the slurries defloculated, leading to an optimum mix of powders before calcination and reaction. The present work is devoted to the mixing of the different oxide and carbonate components in slurries to be synthesized by solid state reaction of the (Zr,Sn)TiO4 (ZST) microwave dielectric and the Pb(Mg1/3Nb2/3)O3 (PMN) compositions. Their rheological properties and zeta potential measurements characterized slurries. These techniques allowed us to optimize the dispersion parameters of the oxide slurries. We have therefore been able to synthesize as well pure PMN and ZST microwave resonators with very high performances.
