Abstract
To control and to improve the homogeneity of a dielectric based on baryum titanate, we have investigated the different stages of the process - ceramic powder, slurry and sintered materials - by automatic image analysis methods. The influence of many parameters has been considered : formulation parameters ; grinding conditions ; particle size and shape ; binder, dispersant and plastification agents; temperature and time of sintering ; ...
