Fabrication of green and sintered bodies prepared by centrifugal compaction process using wet-jet milled slurries
چکیده انگلیسی

Properties of green and sintered bodies prepared by high-speed centrifugal compaction process (HCP) using wet-jet milled slurries were investigated. At 30 vol.% solids loading, the relative packing density of compacted body prepared from wet-jet milled slurry was 67%. On the other hand, the density of compacted body prepared from ball-milled slurry was 56% at the same loadings. The difference in relative densities of the top and bottom of green bodies prepared from wet-jet milled slurry was decreased to one-third of the ones prepared from ball-milled slurry. Moreover, the linear shrinkage of the sintered bodies prepared from wet-jet milled slurries was almost constant at sintering temperatures above 1400 °C; it was found to be increasing for bodies prepared from ball-milled slurries with increasing sintering temperature. Furthermore, activation energy for grain-growth was estimated. The grain-growth of green bodies prepared from wet-jet milled slurries was promoted at lower-sintering temperatures.
