| 1. A powder fabricating apparatus comprising:
a barrel wherein an inlet and an outlet are formed at both opposite ends thereof, respectively;
a screw which is rotationally mounted in the barrel and by which reactant supplied from the inlet moves toward the outlet;
a driving portion for causing a relative rotational motion between the screw and the barrel;
reaction control means for controlling reaction conditions of the reactant which moves in the barrel to induce a chemical
reaction of the reactant, wherein said reaction control means comprises an electron supply device for applying electrons into
the barrel using the barrel and the screw as electrodes for reduction of the reactant; and
a controller for controlling the driving portion and the reaction control means;
wherein said barrel is separated into plural zones, said reaction control means are mounted in predetermined zones, and said
controller controls said reaction control means independently at each zone so that the reaction condition of the reactant
is independently controlled in each zone.
