Abstract: Disclosed are a dielectric substance-electrode assembly in which an electrode is coated with a dielectric and a method for manufacturing the same. The dielectric substance-electrode assembly is formed by forming a lower dielectric electrode constituting a lower portion of an assembly body, sealing a capsule filled with a treated powder and a lower dielectric in which an electrode is formed, and forming an upper dielectric constituting an upper portion of the assembly body using the treated powder which is diffused on and bonded to surfaces of the lower dielectric and the electrode due to sintering heat treatment which is performed by applying an isostatic pressure in a state in which the sealed capsule is placed in a pressure vessel of a heat treatment equipment.

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.
