To solve a problem that an extremely long debinding time is required before sintering in case of the ceramics powder compression molding process, the water binder is used for its easy debinding property in stead of polymer or wax binder. The shape fixing is done by freezing the binding water in the die cavity after compression forming. The vacuum freeze drying is applied for removing the water binder in order to prevent the cracking by the shrinkage of formed powder. It is proved by the experiment that flowability can be improved effectively and samples which have complex shape can be formed easily.
