摘要：

Ceramic injection moulding suspensions consisting of two alumina powders of surface area 9.5 m2g-1 and 0.3 m2g-1 were prepared at 60 vol % ceramic loading in the same organic composition. Cylinders of various diameters of each suspension were companion fired on an identical temperature ramp in nitrogen. For the fine powder, bloating occurred for all diameters above 8 mm. The coarse powder cylinders of 25 mm diameter could be prepared free from internal voids. The problems presented by fine powders during binder removal are discussed in terms of adsorbed layers, water emission and catalytic degradation.
