China Drying Network On August 7, Hunan Provincial Office of the Leading Group for Accelerating the Advancement of New Industrialization issued the “Directory of the Development of Major Key Common Technologies for Strategic Emerging Industries in Hunan Province (2014)â€. The project focused on the major needs of strategic emerging industries, focused on conquering a number of major key common technologies, and promoting the adjustment of the industrial structure and transformation and upgrading of the province.
The key common technology for key materials of solid oxide fuel cells and the preparation of yttrium-stabilized yttrium-zirconium composite powders for SOFC electrolytes: Preparation of yttrium-stabilized yttrium-zirconium composite powder by co-precipitation- spray drying method. The influence of the amount of impurities on the powder properties, the effect of spray drying process and calcining process on the properties of the powders; the preparation of yttrium-stabilized yttrium-zirconium electrolyte materials by tape casting: the yttrium-stabilized yttrium-zirconium electrolyte materials for SOFC prepared by tape casting method. The effects of powder properties, solvent systems, and additives on the dispersion, stability, and rheological properties of the slurry were investigated. The effects of the casting process and sintering process of the graduate student on the performance of the electrolyte ceramic material were investigated.
