Powder properties for good pressing
Pressing green bodies does not work equally well for all ceramic powders. Very coarse powders tend not to give a mechanically stable green body, and very fine powders are difficult to handle due to their low tapping density. Powders with a particle size of 0.5-3µm are generally easiest to press into green bodies. It might be required to add a binder to assure a good mechanical stability of the green body. In this case, remember to remove the binder before sintering by a thermal treatment at 600-800°C in oxidizing atmosphere.
