heal.abstract	Spray drying is a technique used for the production of powders with high chemical homogeneity, consisting of spherical shaped grains with well-controlled particle size distribution, which show very good rheological characteristics. In the present study, the spray drying technique was employed for the production of a homogeneous precursor powder for the synthesis of the superconducting YBa2Cu3O7-x powder. The study, which is concerned with the spray drying of either a solution of precursor nitrate salts or a slurry of precursor oxides, showed that both the powder characteristics and the process yield depend significantly on the drying parameters and that the maximum yield can be obtained within narrow condition limits. A comparison study between the drying of the nitrate salts solution and that of the oxides slurry showed that in the second case the efficiency achieved was much higher.	en
