School of Materials Science and Engineering, Zhejiang University, Hangzhou 310027, Zhejiang, China; 2. Longquan Jinhong Celadon Limited Company, Longquan 323700, Zhejiang, China) Abstract: The celadon body granules were prepared by combining aqueous slurry with fluidization spray drying for direct manufacturing of Longquan celadon. The dispersibility and stability and spray drying behavior of aqueous slurry were studied, and the effect of solid content on the rheological behaviour of slurry and particle size distribution and molding properties of granulated powder pellets were also discussed. The results show that the slurry is Bingham flow behaviour, the slurry with solid content of 40 wt.% has a lower viscosity and shear str
