Abstract: Provided are an apparatus for producing inorganic powder, and a method of producing inorganic powder by using such. The apparatus includes a vaporization part where a condensed-phase precursor is vaporized to obtain a gas-phase precursor, a partial precipitation part where the gas-phase precursor obtained in the vaporization part is partially precipitated to a condensed phase, and a reaction part where the gas-phase precursor remaining after being partially precipitated to a condensed phase in the partial precipitation part reacts with a reaction gas to obtain inorganic powder. An equilibrium vapor pressure of the gas-phase precursor in the partial precipitation part is lower than a vapor pressure of the gas-phase precursor obtained in the vaporization part, and an equilibrium vapor pressure of the precursor in the reaction part is equal to or higher than a vapor pressure of the gas-phase precursor partially precipitated to a condensed phase in the partial precipitation part.

Abstract: An exemplary embodiment provides a method of manufacturing a porous component having a base material layer and a porous layer through one-step laminated-molding, whereby it is possible to provide a manufacturing time when manufacturing a product and to provide a porous component in which the shape and size of a porous layer can be controlled. An implant including the porous component has an increased bone contact ratio, so bone growth between bones can be improved and products fitting to the frames of patients can be easily designed.

Abstract: Provided is a method of producing a nickel nanopowder, the method capable of preventing coagulation between particles and, accordingly, providing a nickel nanopowder having a small average particle size and a low coagulation rate. According to an embodiment of the present invention, the method of producing a nickel nanopowder includes providing a nickel salt and a shell-forming material; nucleating and growing nickel core particles from the nickel salt; forming a shell layer on surfaces of the nickel core particles using the shell-forming material; and removing the shell layer to form the nickel nanopowder.
