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.
